Abstract
A kind of butterfly-shaped tellurium nanoparticles (Te NPs) is prepared in this paper, which have good biocompatibility, their uniform size is about 200 nm, and their photothermal conversion efficiency (η) is as high as 52.9%. Subsequently, a bidirectional freezing method was used to prepare a chitosan hydrogel (CS) with a sponge-like structure, which has excellent porosity and solubility. Its porosity exceeds 75% and can maintain a moisturizing effect for about 16 hours. Then, the prepared Te NPs were introduced into CS to construct a CS/Te antibacterial platform, which was effective against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). These results suggested that CS/Te antibacterial platform could be a promising NIR light-activated antibacterial candidate material for biomedical applications.
