Summary: Utilization of the whole solar spectrum for photocatalysis remains a challenging yet interesting topic. In this study, a series of novel photocatalysts were synthesized with high stability and excellent photocatalytic activity for the decomposition of RhB. By optimizing doping amount and ratios, the degradation rate of RhB was significantly improved compared to traditional photocatalysts. The research also found that simply increasing the size of upconversion nanoparticles is not the most effective way to enhance photocatalytic activity.

Summary: Oral infectious diseases and tooth staining are major challenges in dental healthcare. Researchers have developed copper-doped carbon dots (Cu-CDs) that can inhibit bacterial adhesion and eradicate biofilms in the oral environment without causing harm to surrounding tissues. Cu-CDs also show excellent antibacterial ability against both Gram-positive and Gram-negative bacteria. In addition, Cu-CDs have a better performance in tooth whitening compared to other alternatives, with minimal damage to enamel and dentin. The biocompatible Cu-CDs have great potential for eliminating oral pathogenic biofilms and promoting oral health.
