Comparison of 1,4C-1,4Bis-GNR mediated luciferase expression in (A) PC3 and (B) PC3-PSMA cells in serum-containing media (SCM) and serum-free media (SFM). The optical density of gold was set at 0.0025 and PAE-GNRs loaded with 50 ng pGL3 DNA were employed in all experiments. Values are reported in relative luminescence units (RLU) 48 h post transfection and normalized to protein content (RLU /mg).
