An efficient method based on the photothermal effect for the release of molecules from metal nanoparticle surfaces

Angew Chem Int Ed Engl. 2009;48(23):4166-9. doi: 10.1002/anie.200805303.

Abstract

Please release me: The heat generated when metal nanoparticles absorb light results in a significant increase in the temperature of the environment around the particles and is used to selectively break bonds within a molecular system anchored to the nanoparticle surface (see picture). This process represents an advantageous and more universal method to deliver chemicals locally, while avoiding excessive tissue damage.
