摘要：
A Ag metal core-TiO2 shell (A-@TiO2) composite nanocluster photocatalyst with uniform size and shape was successfully synthesized by a new simple citrate reduction method. The cytotoxicity of colloidal Ag@TiO2 composite nanoclusters was evaluated against cancer (HeLa) cells under UV-vis irradiation. Ag@TiO2 composite nanoclusters were characterized by using UV-vis absorption spectroscopy, TEM, SEM, XPS. XRD, and EDX techniques. It was found that Ag@TiO2 nanoclusters at low concentrations kill HeLa cells by 100%, whereas TiO2 nanoparticles alone kill only ca. 30% at the same concentrations.
