| Abstract | ||
| Cancer photothermal therapy (PTT) depends on the size, and shape of nanoparticles, consequently, on the surface plasmon resonance (SPR) peaks of the gold nanoparticles (GNPs) synthesized by pulsed laser ablation (PLA) method in Dulbecco’s Modified Eagle Medium (DMED), found to be located between (549-580) nm. The size of GNPs measured the calculation of SPR spectra, dynamic light scattering (DLS) methods and analysis of the transmission electron microscope (TEM) images were found to be ranged between (59-116) nm. The concentration of GNPs in prepared colloidal solution found ranged between (8-16) ppm. Irradiation of GNPs which incubated with Hela cells for 24 h by R light for (15,30, and 45) minutes, enhanced the killing percentage especially for GNPs diameters (50- 70) nm. | ||
