Successful non-stick coating repels all bacteria

Researchers have created an optimal anti-stick layer that combines medical technology and the food industry to create a self-cleaning surface that repels even the most dangerous superheroes of bacteria and viruses. .

A team of researchers at McMaster University, Canada has developed a self-cleaning surface that repels all forms of bacteria, preventing the transmission of antibiotic-resistant viruses and other dangerous bacteria in environment from hospital to kitchen.

Researchers at McMaster University created a self-cleaning surface.

This non-stick coating is like a regular transparent coating that can cover door handles, balustrades, brackets and other surfaces, effectively pushing bacteria like MRSA and intestinal bacteria. C. difficile.

The processed material is also ideal for food packaging to prevent accidental transfer of intestinal bacteria such as E. coli, Salmonella and listeria from raw chicken and other foods.

The study was published in a December 13 paper in the journal ACS Nano, led by engineers Leyla Soleymani and Tohid Didar, who collaborated with colleagues from the McMaster Institute for Infectious Diseases Research and the Center. Canadian-based electron microscope based in McMaster.

Inspired by a waterproof lotus leaf, the new surface works through a combination of nanoscale engineering and chemistry. The surface is textured with micro wrinkles that exclude all outer molecules. For example, a drop of water or blood when falling on the surface will pop out. The same is true for bacteria.

`` We are adjusting the structure of the plastic coating so that this material is applicable to all types of surfaces, '' Soleymani said . The surface is also chemically treated to further enhance the waterproofing properties, creating a flexible, durable and inexpensive barrier to regeneration. "

This technology is being used in all types of environments and even in the country. As the world faces the crisis of antimicrobial resistance, we hope it will become an important part of the anti-bacterial toolbox.

The researchers tested the material using two of the most worrying types of antibiotic-resistant bacteria, MRSA and Pseudomonas , in collaboration with Eric Brown of McMaster University's Institute of Infectious Diseases.

Engineer Kathryn Grandfield helped the team verify the effectiveness of the surface by taking pictures of electron microscopes. The results showed that almost no bacteria on the new surface.

Researchers are hoping to partner with a trading partner to develop this new technology trade.
