ZnO nanoparticles can elicit a range of perturbed cell responses in vitro. Exposure to topically applied sunscreens containing ZnO particles may or may not elicit a biological effect in mice.
Dermal absorption and short-term biological impact in hairless mice from sunscreens containing zinc oxide nano- or larger particles.

View SamplesZnO and TiO2 nanoparticles can elicit a range of perturbed cell responses in vitro. Exposure to topically applied sunscreens containing ZnO or TiO2 particles may or may not elicit a biological effect in mice. We aimed to compare the biological responses of immune-competent hairless mice receiving topical applications of commercially available sunscreens with or without metal oxide nanoparticles, with the responses of mice receiving no sunscreen.
Long-term exposure to commercially available sunscreens containing nanoparticles of TiO2 and ZnO revealed no biological impact in a hairless mouse model.
