A) Characterization of AuNRs after each functionalization step using UV-vis analysis. B) TEM image of CD-AuNR-DexAzo complex showing full encapsulation of the rods by DexAzo (scale bar = 50 nm). C) The UV-triggered drug release from DOX-loaded CD-AuNR-DexAzo was evaluated at different irradiation times (0, 5, 10 and 30 s) and monitored using DOX fluorescence scanning at 0, 5, 10, 20 and 30 min after irradiation. Error bars indicate the mean ± SD (n = 3). D) The IR-induced hyperthermia of CD-AuNR-DexAzo complex was monitored by direct temperature measurement using digital thermometer. The nanorods solution was heated to 37 °C prior to laser irradiation. Error bars indicate the mean ± SD (n = 3).
