A far better solution than surfaces coated with antimicrobial chemicals which are just as prone to propelling the survival of the fittest as any other hygienic strategies, material science to looking toward the dragon fly, as TYWKIWDBI informs, for a novel way to repel germs.
Engineers have created a structure out of black silicon, nanopillars, that are very punishing to the cellular membranes of bacteria, just like the topology found on the insects’ wings. Once on this sort of surface, should the microbe move it will be sheared to pieces. Other research projects have yielded nano-structures that inhibit the bacteria sticking at all or being disruptively slippery to discourage cohesion and infection.
