Gold/Chitosan Nanocomposites with Specific Near Infrared Absorption for Photothermal Therapy Applications

Figure 2

Heating effect of the gold nanoparticles with NIR absorption peaks at 820 nm, 880 nm, 980 nm, and 1070 nm, respectively, under the 817 nm wavelength laser exposures. The laser power is 1 W/cm2, and the Au NPs were dispersed in water at a concentration of 1 OD/mL. Inset shows the UV-visible-NIR spectra of the four Au NPs samples.
