Absorbance and photothermal transduction efficiency. (a) Absorbance spectra of Toco-Photoxil tuned at 750 nm (narrow) and 915 nm (broad). (b) Absorbance spectra of FA-Toco-Photoxil showing peak due to FA and Toco-Photoxil. (c) Absorbance spectra of IR780 attached Toco-Photoxil and FA-Toco-Photoxil. (d,e) Photothermal transduction of Toco-Photoxil (750) & Toco-Photoxil (915) at various concentration and same low power setting of laser (~650 mW/cm2). (f) Temperature rise corresponding to laser irradiation on Toco-Photoxil (750), Toco-Photoxil (915), IR780-Toco-Photoxil, FA-Toco-Photoxil, IR780-FA-Toco-Photoxil, water, and PLGA NPs.
