Fig. 7From: RGD-HK Peptide-Functionalized Gold Nanorods Emerge as Targeted Biocompatible Nanocarriers for Biomedical ApplicationsCell viability (MTT) assay after incubation of HeLa (a) and MDA-MB-231 (b) cells with peptide-f-GNRs (using different concentrations of peptide) compared with CTAB-GNRs after 24 h. Cell viability after incubation of HeLa cells with peptide-f-GNRs compared with CTAB-GNRs after 48 h (c). The results are expressed as percentages compared with untreated control cells and represent the mean and standard deviation (sd) of three independent experiments (***P < 0.001)Back to article page
