Paper of the Month: Advancing antimicrobial polymer development: a novel database and accelerated design via machine learning

Zhao et al. accelerate antimicrobial polymer design with a novel database and machine learning.

 

Graphical abstract of selected paper, showing 3 stages of antimicrobial polymer database, machine learning and design principle

 

Drug-resistant microorganisms pose increasing pressure on healthcare systems, underscoring the urgent need for effective disinfectants. In this vein, antimicrobial polymers (AMPs) offer a promising solution by inhibiting or eradicating microbes through diverse mechanisms without fostering resistance. With low toxicity and enhanced durability, AMPs are strong candidates for next-generation antimicrobial agents. However, the design of new AMPs with desired properties is challenging as it is mostly based on time and labor-intensive trial-and-error research.

To address this, Le and collaborators gathered experimental AMP data from various sources, providing a crucial foundation for accelerating AMP design through machine learning (ML). This first open-source database for antimicrobial polymers features 489 entries, including 177 unique polymers that exhibit a range of structures and properties. Advanced algorithms were implemented to identify 32 key descriptors using seven distinct feature selection methods. Additionally, several machine learning models that achieved approximately 85% predictive accuracy for antimicrobial properties were developed. The significance and influence of these descriptors on the antimicrobial characteristics of polymers and proposed guidelines for designing highly effective AMPs were thoroughly assessed.

In summary, this study provides a database, along with the identification of critical descriptors that are expected to offer a strong and informative foundation for researchers to investigate new AMPs in the future.

 

Tips/comments directly from the authors:

  • Data quality is crucial: Accurate, well-prepared data is foundational to the success of machine learning models and the usefulness of new knowledge extracted from such models.
  • Balance novelty with rigor: Innovative methods are highlighted and ensure the approach and conclusions are rigorous and well-validated.
  • Iterate and take feedback seriously: Multiple revisions help improve clarity. Feedback from peers and reviewers must be taken seriously and addressed appropriately.

2023 Polymer Chemistry Lectureship awarded to Professor Miao Hong

We are delighted to announce Professor Miao Hong (Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences) as the recipient of the 2023 Polymer Chemistry lectureship.

 

This award, now in its ninth year, honours an early-career researcher who has made significant contribution to the polymer field. The recipient is selected by the Polymer Chemistry Editorial Board from a list of candidates nominated by the community.

 

Profile picture of Professor Miao Hong  

 

 ‘What impressed me most about Polymer Chemistry is that the manuscripts are being professionally handled with high efficiency.’

 

 

Miao Hong received her Ph.D. degree in 2013 under the supervision of Professor Yuesheng Li from the Changchun Institute of Applied Chemistry, Chinese Academy of Sciences. After a four-year postdoctoral stint at Colorado State University with Professor Eugene Y.-X. Chen, she joined Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences in 2017 as a Full Professor of Chemistry. Research in the Hong group is centred on polymer science, catalytic chemistry, green and sustainable chemistry, and with one of the main interests being the development of novel catalysts and new methodologies for the production of sustainable polymers with controlled structures from renewable feedstocks.

 

To learn more about Professor Hong’s research, have a look at her most recent publication in Polymer ChemistryInsights into the interaction between bis(aryloxide)alkylaluminium and N-heterocyclic carbene: from an abnormal Lewis adduct to a frustrated Lewis pair for efficient polymerizations of biomass-derived acrylic monomers

This is free to access until 30th September 2023, and featured in our most recent Pioneering Investigators collection. You can also check out articles from our previous lectureship winners in our lectureship winners collection.

 

Read our interview with Professor Hong below:

 

How has your research evolved from your first article to you most recent article?

The research in my group is centered on the development of novel catalysts and new methodologies for the production of sustainable polymers with controlled structures from renewable feedstocks. One of major challenges encountered in this area is the conventional catalytic systems, which can effectively polymerize petrochemical monomers, are generally inert/sluggish or uncontrolled toward the polymerization of biomass-derived monomers due to their unique heteroatom-rich structure natures. Take β-angelica lactone as an example, a key downstream chemical of levulinic acid which is available in a total yield of more than 80% from cellulose and classified as one of top biomass-derived compounds best suited to replace petroleum-derived chemicals. However, its polymerization is inaccessible by traditional polymerization methods, such as group transfer, coordination-addition, and radical polymerizations.

 

The first “real” article in my group, accomplished by my first Ph.D. student, is the achievement of the first polymerization of β-angelica lactone through developing a new cooperative Lewis pair catalyst. Accordingly, a heat- and solvent-resistant acrylic bioplastic is effectively synthesized. This work was published in Angew. Chem. Int. Ed. (2020, 59, 2664) and designed as a Hot Paper. On the basis of this work, we further optimized the catalyst structure and established a new and stable Frustrated Lewis pair in our very recently work (Polym. Chem. 2023, 14, 3286 – 3293), which is not only efficient for β-angelica lactone polymerization, but also can mediate fast and controlled polymerizations of methyl crotonate and (E,E)-methyl sorbate, thus establishing a general catalyst for the polymerizations of inert biomass-derived acrylic monomers. Overall, the striking findings from our group and the other groups (e.g. Chen, Zhang, Takasu) shed light on the great potential of cooperative Lewis pair catalysts for efficient polymerizations of challenging biomass-derived monomers.

 

What excites you most about your area of research and what has been the most exciting moment of your career so far?

The most exciting moment of my research career so far should be the successful chemical synthesis of high-molecular-weight biomaterial poly(4-hydroxybutyrate) for the first time via ring-opening polymerization (ROP) of γ-butyrolactone (Nat. Chem. 2016, 8, 42), a biomass-derived lactone monomer commonly referred as “non-polymerizable” in the textbooks and literatures due to low ring strain energy, when I was a Postdoc in Prof. Eugene Y.-X. Chen’ group at Colorado State University. However, such ROP requires extremely low reaction temperature, which severely hampers the possibly industrial applicability of the resultant polymer.

 

Recently, my group established a new polymerization strategy, termed isomerization-driven ROP (iROP). Different from conventionally ring strain-driven ROP, such polymerization is thermodynamically driven by S/O isomerization, thus rendering non-strained five-membered rings highly polymerizable for the first time at industrially relevant temperature of 80-100 °C. I am quite excited about iROP, because it is a simple and powerful strategy which not only can circumvent the unfavorable thermodynamics of ROPs of ‘non-stained’ five-membered lactones, and also presents a fascinating opportunity to convert these abundant, but underexploited renewable feedstocks (e.g. γ-butyrolactone, γ-valerolactone, peach lactone, dihydrojasmone lactone, whiskey lactone) into new sustainable polymers with their key physical properties comparing well to representative commodity polyolefin plastics (Nat. Chem. 2022, 14, 294; Angew. Chem. Int. Ed. 2023, 62, e202217812).

 

In your opinion, what are the most important questions to be asked/answered in your field of research?

One of the most important questions in the field of sustainable polymers should be how to reshape the current petroleum-based polymer industry with sustainable polymers.  That is how to bring the beautiful synthetic schemes and intriguing physical properties of sustainable polymers developed in academia into industrial processes and cost-effective polymeric products. To address this question, cross-disciplinary research (such as polymer chemistry, physics, processing, engineering, and even information technology and artificial intelligence) is highly desirable, and the collaboration between both polymer industry and academic researchers is also essential.

 

How do you feel about Polymer Chemistry as a place to publish research on this topic?

What impressed me most about Polymer Chemistry is that the manuscripts are being professionally handled with high efficiency. Take our recent research article published by Polymer Chemistry as an example. The manuscript was submitted on 17th May 2023, the peer review of which only took two weeks, and accepted fast on13th June 2023.

 

In which upcoming conferences or events (online or in person) may our readers meet you?

The conferences on my schedule are the National Polymer Academic Paper Conference (Oct. 13-17, 2023, Wuhan, China) and IUPAC MACRO 2024 (July 1-4, 2024, Warwick University, United Kingdom).

 

Can you share one piece of career-related advice or wisdom with early career scientists?

You always can find ideas/answers in the literatures when you face the scientific questions.

 

How do you spend your spare time?

Try my best to accompany my family in my spare time. I always feel frustrated to balance work and life.

 

We would like to thank everybody who nominated a candidate for the 2023 Polymer Chemistry Lectureship. The Editorial Board had a very difficult task in choosing a winner from the many excellent and worthy candidates.

 

Please join us in congratulating Professor Hong on winning this award!

Polymer Chemistry Emerging Investigator- Saihu Liao

Profile picture of Saihu LiaoSaihu Liao studied chemistry at Huazhong University of Science and Technology, and obtained his bachelor degree in 2005. After two years of graduate study with Prof. Yuefa Gong at the same university, he joined Prof. Benjamin List’s group at the Max-Planck-Institute for Coal Research (MPI-KOFO), Germany, where he obtained his doctoral degree in organic chemistry in 2011. Then, he returned to China and joined Prof. Yong Tang’s group as a research associate at the Shanghai Institute of Organic Chemistry (SIOC), Chinese Academy of Sciences. In September 2016, he started his independent career at Fuzhou University, where he was promoted to full professor in 2017. His current research focuses on the development of new organocatalysts and new strategies for polymerization, with a special concern to photo-control and tacticity-regulation.

 

Read Saihu’s Emerging Investigator article, ‘Organocatalytic Cationic Degenerate Chain Transfer Polymerization of Vinyl Ethers with Excellent Temporal Control’

 

How do you feel about Polymer Chemistry as a place to publish research on this topic?

We are interested in the exploration of organocatalysis in polymerization, with a focus on the development of organic photocatalysts and chiral catalysts. As one of the leading journals in polymer chemistry with broad readership, Polymer Chemistry is a wonderful place to publish our research on this topic. We quite appreciate the timely and professional processing of the manuscripts, and also the constructive comments and suggestions from reviewers.

 

What aspect of your work are you most excited about at the moment and what do you find most challenging about your research?

The most exciting moment could be the time we found some new catalysts were surprisingly effective. A challenging thing to us is just to predict the performance of a new catalyst, e.g. its ability in the temporal or tacticity control.

Polymer Chemistry Emerging Investigator- Shaofeng Liu

Profile picture of Shaofeng LiuShaofeng Liu is a professor at College of Polymer Science and Engineering at Qingdao University of Science and Technology. He received his B.S. in 2005 from Central South University, obtained his Ph.D. in 2011 from Institute of Chemistry Chinese Academy of Sciences (ICCAS) and Université de Strasbourg (UDS) under the supervision of Prof. Wen-Hua Sun and Prof. Pierre Braunstein. He then joined the group of Prof. Tobin J. Marks at Northwestern University as a postdoctoral fellow (2011-2014). In 2015, he moved to Qingdao University of Science and Technology and started his independent research career. His current research interests include organometallic catalysts for olefin polymerization and organocatalysts for sustainable polymers by ring-opening polymerization. 

 

Read Shaofeng’s Emerging Investigator article, ‘Chromium complexes supported by NNO-tridentate ligands: an unprecedented activity with the requirement of a small amount of MAO’

 

How do you feel about Polymer Chemistry as a place to publish research on this topic?

Polymer Chemistry is a leading journal and a preferred platform to publish important research in the field of polymer science.

 

What aspect of your work are you most excited about at the moment and what do you find most challenging about your research?

Our research interests include the development of organometallic catalysts for polyolefins by coordination polymerization and organocatalysts for sustainable polymers by ring-opening polymerization. Therefore, from the view of both catalytic systems (metal-based or metal-free catalysis) and resultant polymer materials (traditional and nondegradable polyolefin or degradable and recyclable polyester/polycarbonate), there seem to exit conflict of interests, which actually become our most excited aspects. For our current research, the most challenging work is designing simple catalysts to synthesize sophisticated polymers with superior performances.  

 

In your opinion, what are the most important questions to be asked/answered in this field of research?

The activity and selectivity are the most considered aspects for various polymerization reactions. In my opinion, how to balance these two aspects would be the most important question in the field of polymer synthesis.

2022 Polymer Chemistry Lectureship awarded to Dominik Konkolewicz

We are delighted to announce Dominik Konkolewicz (Miami University) as the recipient of the 2022 Polymer Chemistry lectureship.

This award, now in its eighth year, honours an early-career researcher who has made significant contribution to the polymer field. The recipient is selected by the Polymer Chemistry Editorial Board from a list of candidates nominated by the community.

Profile picture of Dominik Konkolewicz  

 ‘I think the fantastic thing about Polymer Chemistry is that the journal has a clear focus on the development and evaluation of polymers, while still covering a wide range of topics ranging from fundamental kinetic analysis and mechanistic work through to 3D printing and bio-applications of polymers.’

 

Dominik Konkolewicz earned a Bachelors of Science degree at the University of Sydney (Australia) in 2006, majoring in Chemistry and Mathematics. He continued at the University of Sydney to complete his PhD (2011) working with Dr. Sébastien Perrier on polymerization kinetics and branched polymer synthesis. He went on to complete postdoctoral research at Carnegie Mellon University in Pittsburgh (USA), working with Dr. Krzysztof Matyjaszewski on mechanisms of complex reactions and applications of precisely defined polymers. In 2014, Dominik joined the Department of Chemistry and Biochemistry at Miami University in Oxford OH (USA) as an Assistant Professor, with promotion to Associate Professor in 2019. He will start as full professor in Fall 2022. The Konkolewicz group explores a wide range of topics in Polymer Chemistry, including radical polymerization mechanisms, dynamically bonded polymer materials, light driven reactions, bioconjugates, and polymer based self-assembly. Dominik has published over 130 research articles in polymer chemistry and polymer science, with a particular focus on developing fundamental science to facilitate the design of functional materials. Dominik can be found on Twitter @PolyKonkol and the Konkolewicz group can be found on Twitter @konkolgroup.

 

Check out Dominik’s recent publication in Polymer Chemistry, A general model for the ideal chain length distributions of polymers made with reversible deactivation’.

This is free to read until 21st July 2022, along with his other publications in our lectureship winners collection. You can find articles from all our previous lectureship winners in the collection too.

 

Read our interview with Dominik below:

 

How has your research evolved from your first article to this most recent article?

My first article in Polymer Chemistry, published as a PhD student, focused on modelling complex polymers. Since then, our group has maintained its core of developing fundamental mechanistic chemistry, while expanding into a wide range of topics such as responsive polymers and biomaterials.

 

What excites you most about your area of research and what has been the most exciting moment of your career so far?

Things that excite me at the moment is the development of basic polymer science that can be connected to ongoing challenges in our fields. Thinking how we use basic science to contribute towards solutions in sustainability and efficiency is really an important area. The most exciting moments in my career are the growth of my students and trainees. Seeing early career scientists and students move towards their long-term career goals and their ability to contribute to ongoing problems is very rewarding.

 

In your opinion, what are the most important questions to be asked/answered in your field of research?

Current and important questions in the field include: how can basic concepts in mechanistic polymer science be translated to next generation materials; and how can we effectively discuss science with the community broadly. We need a balance of fundamental science, but also applying what we know already to current challenges.

 

How do you feel about Polymer Chemistry as a place to publish research on this topic?

I really value Polymer Chemistry as a forum to publish work across the topics of mechanism and kinetics, polymer-based materials synthesis and analysis of structure property relationships across a range of polymer-based materials. I think the fantastic thing about Polymer Chemistry is that the journal has a clear focus on the development and evaluation of polymers, while still covering a wide range of topics ranging from fundamental kinetic analysis and mechanistic work through to 3D printing and bio-applications of polymers.

 

Which of your Polymer Chemistry publications are you most proud of and why?

Clearly this is a really difficult question, because I am very proud of all our group’s publications in Polymer Chemistry. However, if I had to choose one it would be B. Zhang, Z. A. Digby, J. A. Flum, E. M. Foster, J. L. Sparks, D. Konkolewicz, ‘Self-Healing, Malleable and Creep Limiting Materials using both Supramolecular and Reversible Covalent Linkages’, Polymer Chemistry 2015, 6, 7368-7372, DOI: 10.1039/C5PY01214G. This is our first publication on dynamically bonded materials and mechanical testing. I am exceptionally proud of how our team members gained new skills in dynamic chemistry and materials characterization in such a short time, and used these skills to combine two dynamic chemistries to give responsive and stable materials.

 

In which upcoming conferences or events (online or in person) may our readers meet you?

COVID-19 has really negatively impacted our ability to plan for future travel, but I am planning to attend the Fall 2022 ACS meeting in person, as well as a couple of meetings in 2023 such as the 2023 Polymers Gordon Research Conference.

 

Can you share one piece of career-related advice or wisdom with early career scientists?

The advice I would share is don’t be shy about reaching out to trusted individuals (such as colleagues or former advisors) for feedback. Since everyone brings something unique and valuable to the chemistry community, believe in your skills and the importance of your contributions.

 

How do you spend your spare time?

In my time away from the lab, I enjoy spending time with my family and our cats, cooking and baking new recipes, and running or cycling outdoors.

 

We would like to thank everybody who nominated a candidate for the 2022 Polymer Chemistry Lectureship. The Editorial Board had a very difficult task in choosing a winner from the many excellent and worthy candidates.

 

Please join us in congratulating Dominik on winning this award!

Polymer Chemistry Emerging Investigator – Nicholas Warren

Profile picture of Nicholas WarrenNick Warren is an Associate Professor at School of Chemical and Process Engineering at the University of Leeds. He was awarded an Masters in Chemistry from the University of Bristol in 2005 following which he conducted two years industrial research. He then moved to the University of Sheffield where he obtained a PhD in Polymer Chemistry. He continued as a postdoctoral researcher in Sheffield working in the area of polymerisation-induced self-assembly (PISA) until 2016, when he moved to Leeds to start his independent research career. His research group aims to design a new generation of sustainable and functional polymer materials by exploiting the latest advances in both polymer chemistry and self-optimising reactor technologies equipped with advanced online monitoring and computer control. He can be found on Twitter @njwarren1.

 

 

 

Read Nick’s Emerging Investigator article ‘Autonomous polymer synthesis delivered by multi-objective closed-loop optimisation’.

 

How do you feel about Polymer Chemistry as a place to publish research on this topic?

The vision of our research group is to develop technologies which aim to enhance precision and reproducibility in polymer synthesis and it is therefore vital that we target polymer chemists directly. Polymer Chemistry is the ideal avenue for this, and we hope it encourages adoption of new technologies in polymer synthesis labs around the world. Hopefully over the next few years, we can work with others to discover new materials with our platforms by implementing them for more technically demanding polymerisation processes.

 

What aspect of your work are you most excited about at the moment and what do you find most challenging about your research?

The ability to control our systems remotely, means we anticipate that networks of reactors in different labs around the world can communicate via cloud computing to optimise and discover new polymers. We are really excited by the fact that this is bringing artificially intelligent approaches to polymer discovery one step closer!

There are many advantages that flow chemistry affords here, but the challenges associated with polymer solutions in flow means a lot of work is required to optimise the reactor geometries and to provide consistent mixing. However, by working with fluid dynamics experts we are beginning to address these problems, which have traditionally been a major barrier. We are also keen to enable multi-step processes, without human intervention with each characterised in real-time. This includes post-polymerisation processing, and purification. There are also significant challenges in dealing with all sorts of data, which means we’re going to need to tailor our machine learning algorithms to accept this – essentially teaching robots how to do polymer synthesis!

New themed collection: Synthetic methodologies for complex macromolecular structures

We are very pleased to announce the Polymer Chemistry special collection on Synthetic methodologies for complex macromolecular structures, in honour of Professor Yusuf Yağci’s 70th birthday

 

Professor Yusuf Yağci has worked on various aspects of polymer synthesis during his long research career and has developed several new synthetic methodologies to create functional macromolecules. He has benefited from ionic polymerizations, photo-initiated polymerizations, as well as controlled or living radical polymerization techniques. This collection is not just limited to these topics but also aims to reflect the inspiring, creative and entertaining character of Yusuf. The Guest Editors for this collection are:

  • Dr Hatice Mutlu (Karlsruhe Institute of Technology, Germany)
  • Professor Filip Du Prez (Ghent University, Belgium)
  • Professor Remzi Becer (University of Warwick, UK)

 

In their Editorial, Guest Editors Hatice, Filip and Remzi, discuss the impact that Professor Yağci has had on the advancement of many fields, his commitment to the polymer chemistry community and his entertaining character.
