Diagram of Different UV Exposure Methods

Caption

Scientists are using nanoparticle screening on personal care products and finding previously thought toxic chemicals may not be harmful. In Biomicrofluidics, researchers discuss their work successfully using microchips to demonstrate titanium dioxide, a chemical found in most sunscreens, not only is nontoxic but also offers protection against ultraviolet damage to skin cells. This image is a diagram of different UV exposure methods.
