Fig. 2. PSMA-1 ligand mediated cell uptake of 5 nm AuNPs. AuNPs were conjugated with PEG2k-PSMA-1 and PEG2k at ratios of 0, 1 : 8, 1 : 4, 1 : 1 and 2 : 1. The Au content in each cell was verified as a function of PSMA-1 conjugation ratio as determined by ICP-MS. Data are presented as mean ± SD (n = 3).
