Chitosan-Capped Au Nanoparticles for Laser Photothermal Ablation Therapy: UV-Vis Characterization and Optothermal Performances

<div>Evolution of the absorbance spectra of chitosan-capped NPs (CC-AuNPs) synthesized at different <i>R</i> values. (a) The stop-and-return behavior found for <i>R</i> ranging from 1.72 to 2.74. (b) Absorption bands for R ranging from 2.74 to 3.36.</div>
