Abstract
Gold nanoparticles can be used as photodynamic therapy (PDT) agent. Singlet oxygen (1O2) can be generated while gold nanorods and gold bipyramids under laser irradiation directly, which used as efficient PDT agents in vivo. In this study, we prepared the gold nanotriangles (GNTs) through a green synthesis method and demonstrated that 1O2 can be generated when GNTs were irradiated at the wavelengths of 808nm with low power density (500mWcm−2). We also investigated the PDT and photothermal therapy (PTT) effect on the cell viabilities of HeLa cell.
