Dark-field light-scattering images of two cell lines at × 20 magnification after incubation with CTAB-GNRs and peptide-f-GNRs for 2 h. The HeLa (as cancer cells with high level of αvβ3 integrins) cells incubated with peptide-f-GNRs (a) and CTAB-GNRs (b). The MDA-MB-231 (as cancer cells with low level of avb3 integrins) cells incubated with peptide-f-GNRs (c) and CTAB-GNRs (d). It seems that peptide replacement promotes the cellular uptake of peptide-f-GNRs
