Gold nanoparticles, because of their high radiation absorption coefficient and efficient generation of secondary photoelectrons, have been predicted to enhance therapeutic efficacy in radiation therapy. However, high dose for effective treatment limits their use. We have synthesized multifunctional gold nanoclusters (GNCs) that can be used for imaging and radiation therapy. The designed GNCs have been characterized for their physicochemical properties, biocompatibility, and their radiation dose enhancement potential on PC3 cell lines.
Keywords: gold nanoclusters; radiation therapy.
