We produced spherical gold-198 nanoparticles with an average size of 41 nm, good stability, and high radiochemical purity for a promising single agent of radio-photothermal therapy using Curcuma longa rhizome extract as a reducing and capping agent. The combination of in vitro treatment using gold-198 nanoparticles and irradiation of 980 nm wavelength lasers with a power output of 2 W/cm2 induced hyperthermia temperature and exhibited enhancement of the percentage dead on MDA-MB-123 cancer cells compared to gold-198 nanoparticles alone.
