Nanoparticles coated with an inert layer of silica could be used in sunscreens and cosmetics to reduce the potential hazards of these increasingly indispensable materials, new research shows.
The particles still block UV rays, but DNA damage is reduced
In recent years, zinc oxide nanoparticles have been used in sunscreen because of their ability to block ultraviolet radiation and produce less opaque products that are attractive to consumers. This isn’t the only application where nanoparticles are making an impact, being found in everything from cancer drugs to batteries.
