Black Phosphorus Nanosheets as a Robust Delivery Platform for Cancer Theranostics

2D black phosphorus (BP) nanomaterials are presented as a delivery platform. The endocytosis pathways and biological activities of PEGylated BP nanosheets in cancer cells are revealed for the first time. Finally, a triple-response combined therapy strategy is achieved by PEGylated BP nanosheets, showing a promising and enhanced antitumor effect.
