Chemical-free, anti-bacteria plastic skins

A Singapore consortium led by Institute of Materials Research and Engineering (IMRE) is mimicking nature to produce a new chemical-free, anti-bacteria plastic “skins,” local media reported on Monday.

It uses a technology called nanoimprint developed by the institute to make complex nanometer-sized or very tiny patterns on surfaces, local TV broadcaster Channel NewsAsia said.

They mimic the texture of natural surfaces such as the skins of dolphins and pilot whales that are known to have anti-fouling skins.

IMRE said this gives the engineered material “natural” properties such as luminescence, adhesiveness, water-proofing and anti-reflectivity.
