Abstract
A new type of bismuth selenide nanosheet layer material was synthesized by solvent thermal method, which is harmless to human body and can be used in combination with hydrogen peroxide solution as a new type of modern insecticide. The particle size of the bismuth selenide nanosheet material is about 80 nm, and it has good dispersion in water. In this experiment, the antibacterial ability of the material was investigated using Escherichia coli and Staphylococcus aureus as bacterial models and plant pathogens such as strawberry gray mold and tomato gray mold as fungal models. In addition, the in vivo bioassay indicated that Bi2Se3+H2O2 possessed effective control against Pepper Anthrax Disease. The biocompatibility of this material was also investigated using human umbilical vein endothelial cells (HUVEC) as a model, and the results showed that the bismuth selenide nanosheet material has good antibacterial ability and biocompatibility.
