ABSTRACT
Black phosphorus, as a novel two-dimensional nanomaterial, has received a lot of attention from researchers for its unique structure and properties. In recent years, with the increasing cross-sectional research related to black phosphorus 2D nanomaterials in various fields such as materials science, physics, chemistry, biology, and medicine, it has shown great potential for development and application in biomedicine. The excellent photoacoustic properties and good biocompatibility of black phosphorus 2D nanomaterials make them outstanding in tumor diagnosis and treatment. In this paper, the structure and properties, preparation, and functional modification of black phosphorus two-dimensional nanomaterials and their potential applications in the bio-detection and treatment of tumors, as well as the application progress of antibacterial were reviewed.
