Research team creates biofilm-resistant glass for marine environments

A group of researchers led by University of Massachusetts Amherst engineers have created ultraviolet (UV) rays-emitting glass that can reduce 98% of biofilm from growing on surfaces in underwater environments, as reported in the journal Biofilm.

Biofilm is a slimy layer of various types of microorganisms that grows on wet surfaces. “If you look down your sink and touch the inner side of it—that slimy substance is biofilm,” says Mariana Lanzarini-Lopes, assistant …
