DNA templated synthesis of branched gold nanostructures with highly efficient near-infrared photothermal therapeutic effects

Abstract

Herein, we show that DNA nanostructures have great potential as templates for the synthesis of shape-controlled metal nanostructures. In specific, branch-shaped gold nanostructures, which show broad absorption in near the infrared region and have high efficacy in photothermal cancer cell treatment, have been successfully synthesized by using X-shaped and Y-shaped DNA as templates.
