This assembled nanosheet is positively charged and of high specific surface area that captures bacteria through physical adsorption and electrostatic interaction. Under visible light irradiation, this photoactive nanosheet concurrently generates massive heat and produces substantial reactive oxygen species to inactivate bacteria. In comparison with bare gold nanoclusters and amine-functionalized graphene oxides, this nanosheet appears an enhanced antibacterial activity >5-fold towards Gram-postive and Gram-negative bacteria. Moreover, a nanosheet modified silicone surface was employed as a model of implant devices, which showed superior antibacterial efficacy against bacterial colonization in vitro. This work demonstrates that the assembled nanosheet is a promising novel strategy in the construction of next generation antimicrobial agent for synergistic bacterial capture, oxidative stress, and photothermal ablation in the biomedical and environmental fields.Bioaccumulation and toxicity of per-and polyfluoroalkyl substances and metal in plants have been confirmed, however their contamination in soil and plants still requires extensive investigation. In this study the combined effects of chlorinated polyfluoroalkyl ether potassium sulfonate (F53B) and chromium (Cr) on water spinach (Ipomoea aquatica Forsk) were investigated. Compared with each single stress, the combination of F53B and Cr (VI) reduced the biomass and height and increasingly accumulated in the roots and destroyed the cell structure. Besides, the co-contamination led to the immobilization of F53B and Cr (VI) in soil, which affected their migration in
