In vitro evaluation of the photothermal effect of AuNR@BSA. a The photothermal temperature of AuNR@BSA and AuNR@CTAB as a function of laser irradiation time (SPR absorbance about 1, 1064 nm, 1 W/cm2). b NIR-triggered temperature increasement of PBS, AuNR@CTAB (OD = 1), and AuNR@BSA (OD = 1) as a function of laser irradiation intensity (1064 nm, 0.35 to 1 W/cm2). c NIR-triggered temperature increasement of AuNR@BSA and AuNR@CTAB with different absorbance for 10 min laser irradiation (1064 nm, 1 W/cm2). d Photothermal conversion of AuNR@BSA (OD = 1) under three cycles of irradiation (1064 nm, 0.5 W/cm2). e Thermal image of PBS, AuNR@CTAB (OD = 1), AuNR@BSA (OD = 1) under irradiated with NIR laser (1064 nm, 1 W/cm2) at a time interval of 5 and 10 min.
