Ultraviolet-emitting glass has been created: a solution to the problem of biofilm on ships

Biofilm formation on surfaces underwater is a costly nuisance for the Navy and marine research. A new invention by engineers at the University of Massachusetts Amherst may be the solution to this problem: glass that emits ultraviolet rays to destroy biofilm at its source.

Biofilm is a slimy layer of microorganisms that infects the underwater environment. It increases the resistance of ships and interferes with the operation of sensors. Current methods of combating biofilm are based on the use of short-acting chemical solutions that can harm the ecosystem.

This new glass disinfection solution uses ultraviolet (UV) light. The researchers embedded silicon dioxide nanoparticles into glass. When ultraviolet light hits the glass, these nanoparticles disperse the rays evenly across the entire inner surface. Result? A permanently "luminous" glass surface that emits ultraviolet rays strong enough to destroy 98% of biofilm compared to untreated glass.

The team is now optimizing their invention for long-term use and studying its suitability for underwater camera lenses.
