(a) Viabilities of PC3, DU145 and LNCaP cells from treatments with nGO@cPEG and nGO@DOX-cPEG flakes including free DOX and with or without NIR exposure (a: P<0.05; b: P<0.01; c: P<0.05). (b) Confocal images of PC3, DU145 and LNCaP cells following treatment with nGO@DOX-cPEG flakes. Lysotracker green was used for tracking lysosomes. Scale bar, 30 μm. (c) Fluorescence-activated cell sorting measurements for quantitative cellular uptake analyses of nGO@DOX-cPEG flakes using PC3, DU145 and LNCaP cells in a concentration- (a, c, e) and time-dependent manner (b, d, f). cPEG, chitosan-polyethylene glycol; DOX, doxorubicin; nGO, nanodimensional graphene oxide; NIR, near-infrared.
