Researchers have found that less toxic, naturally occurring nanoparticles have unique optical properties and may one day replace metal-based nanoparticles used for biomedical applications.

Nanoparticles from English ivy were found block UV light more efficiently, were less toxic and were easily biodegradable compared a nanoparticle used in many of today’s sunscreens.

Apparently the nano zinc in sunscreens is getting into our bodies and who knows what it can do to us. At least that would be a reasonable conclusion to draw if you read The Australian today.
