A self-cleaning surface that can repel all forms of bacteria and prevent the transfer of superbugs has been developed, scientists said. The new plastic surface, which could be used in a range of settings including hospitals and kitchens, is a treated form of conventional transparent wrap. It can be shrink-wrapped on door handles, railings, IV stands and other areas that can be magnets for bacteria such as MRSA and C. difficile, scientists say. The material is also ideal for food packaging, where it could stop the accidental transfer of bacteria such as E. coli, salmonella and listeria, according to a study published in the journal ACS Nano. Inspired by the water-repellent lotus leaf, the new surface works through a combination of nano-scale surface engineering and chemistry.
