Fig. 2From: RGD-HK Peptide-Functionalized Gold Nanorods Emerge as Targeted Biocompatible Nanocarriers for Biomedical ApplicationsZeta potential of CTAB-GNRs (+ 35 mV), peptide-functionalized GNRs (+ 29 mV), and antisense oligonucleotides (ASO-conjugated GNRs (− 6 mV). The results represent the mean and standard deviation (sd) of three independent experiments (***P < 0.001)Back to article page
