Figure 6

Biological application of the AuNRs with different capping ligands. (a) Biotoxicity of the AuNRs with the capping ligand of CTAB, PVP, DEA, and TSC, respectively, at different concentrations, showing the viability of the cells after incubation with the AuNRs for 3 days. (b) Viability of the cells after photothermal treatment with TSC-capped AuNRs of different concentrations.
