As you know, bacteria and viruses are pretty fast.multiply, getting on any surface. Therefore, the cleaning and disinfection of surfaces from microorganisms is extremely important both in everyday life, and, for example, during operations. But you wouldn’t have to clean anything if bacteria and viruses could not “catch on” from the very beginning. And researchers at McMaster University seem to have created material that repels even the most deadly superbugs.
How to defeat bacteria and viruses?
McMaster University Research Teamdeveloped a self-cleaning surface that can "reflect all forms of bacteria." In appearance, it is not much different from ordinary plastic. The development can be applied in conditions that require high purity, from hospitals to kitchens. The material is also ideal for food packaging, where it can stop the accidental transfer of bacteria such as E. coli, Salmonella and Listeria from raw chicken, meat and other foods. This is what the Sciencedaily publication writes with reference to the scientific journal ACS Nano, where the corresponding article was published.
The study was led by LeilaSoleimani and Tohida Didara, who collaborated with their colleagues at the McMaster Institute of Infectious Diseases and the McMaster Canada Center for Electron Microscopy. The new surface is a combination of nanoscale surface engineering and chemistry. The surface is textured with microscopic “wrinkles”, which exclude all external influences. Drops of water or blood, for example, just bounce off. The same goes for bacteria.
We structurally “tune” this plastic, -says Leyla Soleimani, a physics engineer. This material gives us something that can be applied to all kinds of things. The surface is also chemically treated in order to further increase the repulsive properties, which leads to the creation of a barrier that is durable and inexpensive to manufacture. Since the world is facing a crisis of antimicrobial resistance (ed. Lately the emergence of super-resistant strains of bacteria is really a real problem), we hope that the new material will become an important part of antibacterial tools.
Researchers tested the work of their material,using two forms of antibiotic-resistant bacteria at once: Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa. The material demonstrated its repulsive ability by 87%. And Escherichia coli did not manage to “move” to new material at all. Scientists were able to verify the effectiveness of the surface by looking at it in real time using an electron microscope, which showed that virtually no bacteria could move to a new surface. We regularly write about such developments on the pages of our portal. So stay with us so you don’t miss anything.
This is interesting: An antibiotic has been created that kills "super bacteria"
Moreover, it is also interesting that viral formsalso cannot effectively settle on such materials. And viruses, as you know, are much smaller than bacteria. So the potential for using the material for medical purposes is extremely high. Researchers are currently working on the commercial application of the new technology. After all, apparently, her potential is simply huge.
