The new plastic surface – a treated form of conventional transparent wrap – can be shrink-wrapped onto surfaces, such as handles, that can be magnets for bacteria such as MRSA and C. difficile. The treated material is also ideal for food packaging, where it could stop the accidental transfer of bacteria such as E. coli, Salmonella and listeria from raw chicken, meat and other foods, as described in a paper published by the journal ACS Nano.
