Meet our authors: an interview with Kamil Godula

Welcome to a new entry on our series of interviews in the ChemComm blog! We want you to know more about some of the early career investigators who choose to publish their exciting work with us.

Next in this series is Dr Kamil Godula, from the University of California San Diego. Read the full interview below.

———-

What inspired you to become a scientist?Kamil Godura

For me, it was my curiosity in finding out how the world around me works. My science teachers seemed to be the ones that had the answers to many of my questions and that had inspired me to pursue a scientific path.

I’ve always been intrigued by the ability of biologists, physicists and mathematicians to describe our world and try to pinpoint its fundamental principles. But ultimately, it was chemistry that captured my imagination for being a transformative science rather than a descriptive one. Becoming a chemist has allowed me to unleash my creativity and imagination.

Follow us on Twitter!How did you find out about ChemComm?

I became familiar with ChemComm as a new graduate student. Ever since, I’ve enjoyed the high quality of the research papers and the broad scope of topics that appear in the journal. Reading ChemComm is always a great way to gain a fresh perspective on and a new inspiration for my research.

What was the motivation behind the work described in your article? What interested you in this area?

My research team is interested in studying the role of carbohydrates in modulating biological events at the boundary between cells and their surrounding environment. The structures of these glycans, as they are called, can be recognized by protein receptors and many pathogens have evolved to target glycans to gain entry into their hosts.

What is interesting is the fact that the interactions of individual glycans and proteins are typically rather weak to be specific in a biological setting. To compensate for that, multiple copies of glycans are typically displayed by lipids and proteins found on cell membranes. My lab is interested in understanding how the three dimensional presentation of glycans on our cells affects the ability of influenza viruses to bind and initiate infection.

Once we gain a better understanding of these higher-order binding interactions between the virus and our cells, we may be able to design better drugs to fight influenza.

Reading ChemComm is always a great way to gain a fresh perspective on and a new inspiration for my research.

Dr Kamil Godula, University of California San Diego

Why did you choose ChemComm to publish your work?

Our research is very interdisciplinary and involves carbohydrate and polymer synthesis, microarray platform development, as well as virus production and biological assays. At the same time, chemistry is always the central enabling science in all of our research. Therefore, ChemComm was a natural choice to publish our study.

Where do you see your research heading next?

Wikipedia

Our microarray platform has begun to reveal very interesting effects of glycan organization on their recognition by intact influenza viruses. We are currently investigating how the initial binding of the viruses to the “sugar landing pad” on epithelial cells correlates with their ability to enter the cells and initiate infection. We are also expanding this platform to enable the discovery of more effective antiviral drugs.

If you could not be a scientist, but could be anything else, what would you be?

Definitely a jazz musician. Benny Goodman has always been my great inspiration; I’m fascinated by the complexity and beauty of his improvisations and wonder what it’d feel like to master the clarinet the way he did.

Terpene analogues bear safer pesticides

Image of ants crawling over a plantTweaking the natural substrates of terpene synthase enzymes could lead to less toxic pesticides and swathes of other important biologically-active compounds, according to UK researchers.

Terpene synthases generate a huge variety of natural compounds with important functions in all forms of life. Many plants emit volatile terpenes to repel predators, including insects, so there is considerable interest in creating new terpene analogues for pesticides. Insects, however, have a very sophisticated ‘nose’ for these compounds and may ignore even closely-related analogues.

Hierarchical 3D immunoassays – higher loading, lower fouling

Iain Larmour is a guest web writer for ChemSci. He has researched a wide variety of topics during his years in the lab including nanostructured surfaces for water repellency and developing nanoparticle systems for bioanalysis by surface enhanced optical spectroscopies. He currently works in science management. In his spare time he enjoys reading, photography, art and inventing.

If you are producing an immunoassay there are two key parameters you need to understand and optimise: surface structure and surface chemistry. Get these two parameters right and you will optimise the sensitivity of your immunoassay. 

Although there have been a multitude of 3D surface generation routes reported, they are generally complicated and require a lot of additional steps. Although these 3D surfaces lead to high probe loading levels they also often lead to high levels of non-specific protein absorption, undoing any good the surface structure would have led to. 

Jinghua Yin and team from the State Key Laboratory of Polymer Physics and Chemistry at the Changchun Institute of Applied Chemistry have focussed on both properties to generate a much improved immunoassay. 

 Firstly they generated a 3D surface using UV irradiation of polystyrene spheres onto a substrate; they then grafted polymer brushes to the sphere surface. The polymer brushes not only further increased the surface area (more than doubling it from the bare sphere surface) but also acted as an anti-fouling agent, reducing the amount of non-specific binding observed by up to 90%. 

Antibody loading on different surface types showing increasing loading levels

 

The commonality of the functional groups on the polymer brushes mean that any antibody can be attached to the prepared surface. To find out the details of how to make these surfaces and try them out on your own immunoassays, read the paper today!

Sweating the small stuff – paper-based cystic fibrosis screening

Iain Larmour is a guest web writer for ChemSci. He has researched a wide variety of topics during his years in the lab including nanostructured surfaces for water repellency and developing nanoparticle systems for bioanalysis by surface enhanced optical spectroscopies. He currently works in science management. In his spare time he enjoys reading, photography, art and inventing.

Cystic Fibrosis (CF) is one of the most common inherited diseases, with 1 in 3000 Caucasians a carrier of the single gene mutation. One feature of CF is abnormally elevated sweat anions, and this feature is exploited in the gold standard diagnostic tests.
 
However, gold standard in this case does not stand for inexpensive nor ease of use. This leads to limited availability and the requirement for large volumes of sweat; not the easiest of things to get from newborn babies who need to be screened for CF.
 
In a recent ChemComm article, Xuan Mu, Zhi Zheng and team from the Institute of Basic Medical Sciences at Peking Union Medical College have reported the development of a paper-based analytical device that can detect sweat on the skin using much smaller volumes than current tests.
 
The team use a colorimetric detection approach with stacked functional papers (paper discs produced with a hole punch). The key element is the anion exchange layer which converts sweat anions into hydroxide ions, leading to a local alkalization and subsequent change in the colour of another pH paper layer. 
 

The stacked paper based diagnostic device developed by the authors


The authors have applied their diagnostic device to real patients and can clearly discriminate between CF and non-CF patients with a clinical reference point. With the cost of these tests being less than a dollar and being wearable, the authors have opened up a new opportunity for the screening of CF.

Ionic liquids come up smelling of roses

Carolyn Devlin writes about a hot ChemComm article for Chemistry World

A new perfume delivery system has been developed by chemists in the UK as a way of keeping sweet smells around for longer. This cleverly designed system tags fragrance alcohols – such as 2-phenylethanol, which has a rose-like scent – onto odourless ionic liquids. In the tagged form, the material has no smell. However, when it comes into contact with water, the link is broken and the fragrance is released – along with its sweet scent.

Fragrance alcohols are typically volatile, so their scent can be lost soon after a perfumed product is applied. A lot of research has been dedicated to finding ways to keep scents around for longer.

Hydrogel with a basic instinct for drug delivery

Christopher Barnard writes about a hot ChemComm article for Chemistry World

A self-assembling hydrogel with nanofibres that specifically capture and release anti-inflammatory compounds has been created for applications in targeted drug delivery. The drug naproxen is only unleashed from the gel in basic solvents, a trait that could be exploited to avoid naproxen’s undesirable side effects.

Painkillers and anti-inflammatory drugs, such as naproxen and ibuprofen, are ubiquitous in the management of many diseases and injuries. However, even these well-established medications can cause stomach ulcers and other gastrointestinal disorders. Side effects most commonly arise when the drugs are taken for an extended period of time, as in the long-term treatment of arthritis with naproxen. One way of preventing these painful consequences is to encapsulate drugs to restrict their availability in certain parts of the body and target their release to others.

Rotaxane Pulley – To Me, To You

Iain Larmour is a guest web writer for ChemSci. He has researched a wide variety of topics during his years in the lab including nanostructured surfaces for water repellency and developing nanoparticle systems for bioanalysis by surface enhanced optical spectroscopies. He currently works in science management. In his spare time he enjoys reading, photography, art and inventing.

Mechanically interlocked molecules have received ever increasing focus over the last number of years due to their potential to mimic the function of macroscopic devices in the molecular world.

Examples include molecular elevators and molecular muscles and with this Communication Zheng Meng and Chuan-Feng Chen of the CAS Key Laboratory of Molecular Recognition and Function at the Chinese Academy of Sciences in Beijing have added pulley-like shuttling motion to the toolkit.

Molecular pulley system powered by acid and base

Molecular pulley system powered by acid and base

Using their previously reported* triptycene-derived crown ether host and combining it with a linear guest with three dibenzylammonium and three N-methyltriazolium sites, they have made a molecular pulley system that mimics the plain rotary motion and linear translocation of full sized pulleys. The movement is powered by acid or base leading to one end of the cable-like guest moving towards the host while the other moves away (picture).

The researchers have not only added to the toolbox of molecular motion components but also provided new insights towards further developing molecular machines.
