Smart bandages you press for antibacterial action

03 May 2016

Written by Jason Woolford for Chemistry World

Researchers in China have developed capsules for use in bandages that can store antibacterials and control their activity, aiding in the fight against antimicrobial resistance.

The smart bandage contains silver nanoparticles (AgNPs) packaged in carbon below a layer of phosphate buffered saline (PBS). Pressing the bandage causes the layers to interact, releasing the antibacterial silver particles

Bacterial strains resilient towards multiple drugs are an increasingly common and dangerous part of the 21st century. With repercussions global in scale, innovative devices are needed that deliver antibacterial agents precisely and instantly so bacteria cannot adapt.

Winners at the 26th IUPAC International Symposium on Photochemistry

27 Apr 2016

By Aliya Anwar.

Congratulations to all the poster prize winners at the 26^thIUPAC International Symposium on Photochemistry which took place in Osaka, Japan from the 3^rd– 8^thApril 2016. The symposium was well attended with more than 600 worldwide delegates attending. Journal of Materials Chemistry A and Journal of Materials Chemistry C were two of the RSC journals providing awards for the best Young Researcher Oral Presentation, Student Oral Presentation and Student Poster.

The scientific program for the conference set out to cover all of the major disciplines of contemporary photochemistry-related science including physics, biology, medicine, materials science, engineering, and technology. A range of scientific events composed by plenary lectures, invited talks, oral presentations, and poster sessions. One of the main aims was to generate new research ideas, by providing a unique opportunity for scientific interaction and exchange of ideas among participants.

The conference chairperson Professor Tetsuro Majima was on hand to present the prizes to the winners pictured below. Further information can be found on the website along with a full list of all the winners.

By Aliya Anwar.

Many congratulations to Professor Chengtie Wu (Shanghai Institute of Ceramics, China) for winning the 2015 Journal of Materials Chemistry Lectureship.

Chengtie Wu is currently a Professor at the Shanghai Institute of Ceramics of Chinese Academy of Sciences. He obtained his bachelors degree at the Dalian Polytechnic University in China by studying Materials Science and Engineering from 1996 to 2000. His main focus of study was on the surface properties of biochips. He then studied bioactive ceramics for bone tissue repair for his doctorate at the Shanghai Institute of Ceramics, Chinese Academy of Sciences where he is currently based. Below is his recently published article on bone tumour cells.

Colour-changing polymer adapts camouflage to vegetation and desert

12 Apr 2016

By Aliya Anwar.

Written by Harriet Brewerton for Chemistry World

Scientists are closer to producing outfits for the armed forces that change colour to match surroundings when soldiers move from a forest to a desert.

Clothing that adapts quickly to camouflage troops in different places would protect them against visual detection. Sunglasses, anti-glare mirrors and electronic display devices all use conducting polymers to change colour. Now, Wei Huang and Hong Meng at Nanjing Tech University, and their team in China, have designed an organic polymer that is green in the reduced state but oxidises and turns a sandy-brown when a low voltage is applied.

The full article can be read in Chemistry World.

Squid beak insight shifts chitosan composites up the pecking order

12 Apr 2016

By Aliya Anwar.

Written by Christopher Barnard for Chemistry World

Inspired by squid beak, researchers in the US have created a lightweight composite from naturally abundant components that can be rigid at one end yet bendy at the other.

With a chitin beak and serrated chitin teeth on their arms and tentacles, nothing showcases biopolymer versatility quite like the giant squid. Unlike many strong biological materials, such as nacre in pearls or chiton mollusc teeth made of magnetite, chitin is devoid of metals and derives its extreme properties solely from organic molecules.
