We have prepared enzyme-mimic Au-Pt nanocomposites (NCs) for catalyzing the decomposition of reactive oxygen species. After surface modification, the Au-Pt NCs can be readily internalized and retained by human skin cells and also can effectively reduce cellular oxidative stress. We have demonstrated that the active and biocompatible Au-Pt nanocomposites can be applied for preventing cell damages by scavenging cellular reactive oxygen species induced by ultraviolet irradiation, indicating potential uses for the prevention and therapy of ROS-mediated diseases.
