Nanoparticles are used in many commercial products catalysts
to cosmetics. A review published today in the Science and Technology of
Advanced Materials by researchers in Sweden and Spain describes recent work on
the 3 main nanoparticles used in photocatalytic, UV-blocking and sunscreens.
Nanoparticles are currently used in commercial products
ranging from catalysts, polishing media and magnetic fluids to cosmetics and
sunscreens. A new review by researchers in Sweden and Spain describes recent
work to optimize the synthesis, dispersion and surface functionalization of titania,
zinc oxide and ceria – the three main nanoparticles used in photocatalytic,
UV-blocking and sunscreen applications.
