Characterizations of the MNPs and their PDT effect. 31P{1H} (202.3 MHz, 293 K) of a cPt and b M. c AFM image of the MNPs. d DLS and e Zeta potential results of the NPs formed from mPEG-b-PEBP and RGD-PEG-b-PEBP before (black line) and after (red line) encapsulation of M. f The fluorescence intensity changes at 532 nm of the solution containing SOSG and TPP (M or MNPs) after different periods of irradiation (671 nm, 0.5 W cm–2). g The fluorescence intensity changes at 532 nm of the solution containing SOSG and TPP (M or MNPs) after irradiation (671 nm, 0.5 W cm–2, 10 min) in the absence and presence of NaN3 (10.0 μM). h Time-dependent density functional theory molecular simulation of M. The data are expressed as means ± s.d
