Abstract

With recent scientific developments, Photodynamic therapy (PDT) offers the promisie to become incorporated into the mainstream of cancer therapy. Noble metal based nano-PDT is increasing due to its advantages in the field of biomedicine. In this study, noble metal based Ag@SiO <subscript>2</subscript> core-shell nanoparticles were synthesized and to confirm the core-shell structure they were characterized by UV-vis, XRD, FTIR, TEM, and EDX. Our data confirm that core-shell type Ag@SiO <subscript>2</subscript> nanoparticles maintain its ability to kill cancer cells upon light irradiation. This shows that SiO <subscript>2</subscript> shell may not only prevent aggregation but it also may enhance the photodynamic activity of Ag nanoparticles.<br /> (Copyright © 2019 Elsevier B.V.
