Black phosphorus nano flake (Thickness 2-3nm)

Black phosphorus material can be used as an efficient photosensitizer,which can produce a large amount of singlet oxygen and can be used in photodynamic therapy.Black phosphorus itself has no toxicity to a variety of cells. After polyethylene glycol(PEG)is modified by electrostatic adsorption,the oxidation of black phosphorus can be effectively reduced and the stability can be significantly improved.It can not only improve the biocompatibility of the material,but also facilitate the further functional modification of the material.Black phosphorus nano flakes can produce local high heat under 808 nm laser irradiation.On the one hand,they can be used for photothermal therapy of tumors,on the other hand,they can also drive the release of drugs.
