Photo-responsive chitosan/Ag/MoS2 for rapid bacteria-killing

Bacterial infection is a serious problem threatening human health. The chitosan (CS)-modified MoS2 coating loaded with silver nanoparticles (Ag NPs) was designed on the surface of titanium (Ti) to kill bacteria rapidly and efficiently under 660 nm visible light. Ag/MoS2 exhibited high photocatalytic activity due to the rapid transfer of photo-inspired electrons from MoS2 to Ag NPs, resulting in higher yields of radical oxygen species (ROS) to...
