Effect of IR and/or AuNPs on the adhesion of human cancer cells in vitro. (A) DU145 (prostate) and (B) A549 (lung) cancer cells treated with 1 mM AuNPs 24 h prior to exposure to either 2 or 5 Gy (6 MV X-rays) and after 24 h the cells were trypsinised and plated in 6 well plates. After 4 h, the number of adhered cells in a 62,500 μm2 area were counted. Results are expressed mean ± SEM of 3 replicates. Significance of different IR doses with AuNPs on cell adherence compared to untreated controls is shown as * p < 0.05.
