Clonogenic survival assay of prostate cancer and prostate epithelial cells following treatment with RALA-AuNP complexes and radiation. Cells were exposed to 1 µg of citrate-AuNP or RALA-AuNP (25:1 w:w) for 6 h. Excess nanoparticles were then removed and cells irradiated with 0–6 Gy (160 kV—A, C, E or 6 MV—B, D, F) then incubated under normal cell culture conditions for 12 days before scoring. Panels represent cell survival with various gold treatments compared to radiation alone. A and B DU145; C and D PC-3; E and F PNT2-C2. A linear quadratic (LQ) curve fit was applied
