(A) Absorption spectrum of an aqueous dispersion of Au@PolyCD after (a) and before (b) stirring overnight with a thin film of SRB. Difference absorption spectrum between a and b (c) and absorption spectrum of a solution of PolyCD (2 mg mL⁻¹) encapsulating SRB at the same concentration as in a (d); spectra c and d are multiplied for a factor of 10 for sake of clarity. The inset shows the size distribution of sample a measured by DLS. (B) Temperature changes observed upon 808 nm CW laser irradiation (6 W cm⁻²) of the Au@PolyCD@SRB complex (sample a).
