Photoregulated release of caged anticancer drugs from gold nanoparticles

J Am Chem Soc. 2009 Apr 29;131(16):5728-9. doi: 10.1021/ja900591t.

Abstract

An anticancer drug (5-fluorouracil) was conjugated to the surface of gold nanoparticles through a photocleavable o-nitrobenzyl linkage. In this system, the particle serves as both cage and carrier for the therapeutic, providing a nontoxic conjugate that effectively releases the payload upon long wavelength UV irradiation.
