Strong fluorescence and high catalytic activities cannot be achieved simultaneously due to conflicts in free electron utilization, resulting a lack of bioactivity most near-infrared-II (NIR-II) fluorophores. To circumvent this challenge, we developed atomically precise Au22 clusters with strong NIR-II ranging from 950 1300 nm exhibiting potent enzyme-mimetic through atomic engineering create active Cu single-atom sites. The Au21Cu1 show 18-fold higher antioxidant, 90-fold catalase-like,...
Selenium (Se) and tellurium (Te) nanomaterials with novel chain-like structures have attracted widespread interest owing to their intriguing properties. Unfortunately, the still-unclear catalytic mechanisms severely limited development of biocatalytic performance. In this work, we developed chitosan-coated Se nanozymes a 23-fold higher antioxidative activity than Trolox bovine serum albumin coated Te stronger prooxidative effects. Based on density functional theory calculations, first...
