Dual Plasmonic Gold Nanostars for Photoacoustic Imaging and Photothermal Therapy

Abstract

Photoacoustic amplitude increase with longer wavelength source and with silica coating of DPGNS. The in vivo photothermal capability of DPGNS resulted in a significant decrease in the tumor cellular area. DPGNS exhibited potential for single node diagnosis and therapy with longer wavelength facilitating deeper imaging and therapy.
