Multiphoton molecular photorelease in click-chemistry-functionalized gold nanoparticles

Small. 2011 Dec 2;7(23):3271-5. doi: 10.1002/smll.201101753. Epub 2011 Oct 20.

Abstract

Yellow-green controlled photorelease: probes click-linked to peptide-coated gold nanospheres by a triazole ring can be released in living cells under a focused 561 nm laser at low power. Photocleaving follows a three-photon event stimulated by the excitation of the localized surface plasmon resonance.
