Figure 3.
Clonogenic survival fraction of PC3 cells treated with goserelin-conjugated gold nanorods (gAuNRs) and pegylated gold nanorods (pAuNRs) for 24h prior to irradiation with 6MV beam. Inset table shows radiosensitization enhancement fraction (REF) obtained at 10% survival fraction. Conjugated nanoparticles, gAuNRs, were found to radiosensitize cancer cells significantly more than pegylated gold nanoparticles (p<0.0001).
