Thin Film Repels Bacteria

Thin Film Repels Bacteria
A self-cleaning, thin film able to repel bacteria could have important applications ranging from hospitals to the food industry.

Inspired by the self-cleaning lotus leaf, the transparent plastic film developed by researchers from McMaster University features a hydrophobic surface textured with microscopic wrinkles that prevent liquids and bacteria from attaching. The team also treated the film with a fluorine-based chemical to further enhance its repellant qualities, resulting in thin material able to repel even antibiotic-resistant bacteria. According to the team, the film could be shrink-wrapped onto objects such as door handles or IV poles, as well as used to package food.
