Intracellular NIR-responsive NO release profiles of GO-BNN6 nanomedicine under the excitation of 808-nm NIR light detected with RBSP: (A) qualitative observation under fluorescence microscope; (B) flow cytometry statistics of the fluorescence intensity of treated 143B cells. (C) Cytotoxicity comparison of GO-BNN6 and GO-BNN6 plus NIR irradiation (808 nm NIR laser, 0.2 W/cm2, irradiated 2 min) at different concentrations against 143B cells.
