Modeling of temperature elevation by PTT and MTT assay of nanoparticles. (A) The photothermal profiles of pure water and aqueous dispersions of BSA–AuNRs with 30 ppm of BSA–AuNRs examined using 808-nm laser irradiation with a different power density of 1.4 and 2 W/cm2. (B) Cell viability of CTAB–AuNRs and BSA–AuNRs at different concentrations (5–30 ppm). (C) Relative cell viability in response to 808-nm laser irradiation with a power density of 2 W/cm2 after incubation with or without 30 ppm of BSA–AuNRs cell culture media. One-Way ANOVA and Tukey post hoc analysis. (n = 3) **P < 0.01; ***P < 0.001; ****P < 0.0001.
