(a) Comparison of the photothermal conversion efficiencies of GNPs in water solutions with (measured) and without (predicted) the influence of the reabsorption of scattering. (b) Predicted absorption (Cabs) and scattering (Csca) cross sections for the different GNPs. (c) Predicted absorption efficiency factor, Qabs, and (d) predicted Au mass normalized absorption cross sections of the different GNPs. Qabs is the normalized Cabs by the geometric cross-sectional area of GNPs. The effective cross-sectional area of a GNR is calculated from their volume-equivalent nanospheres. Statistical significance is indicated with asterisks: * p < 0.05; ** p < 0.01; *** p < 0.001 **** p < 0.0001; ns: p > 0.05.
