New study shows how nanopillars of different heights on the wings of dragonfly literally rip bacteria apart.
Surfaces that obliterate bacteria have always been in demand. Last year, for instance, a group of Dutch scientists used a new type of plastic resin infused with quaternary ammonium salts to develop a 3D-printed tooth that is reportedly capable of killing up to 99-percent of oral bacteria. As part of a new study, researchers from Nigeria and Australia have created yet another bacteria-annihilating surface, featuring a “bed of nails” that literally rip these pesky microbes apart.
