Inspiration from chemical photography: accelerated photoconversion of AgCl to functional silver nanoparticles mediated by DNA

Chem Commun (Camb). 2011 Sep 7;47(33):9426-8. doi: 10.1039/c1cc13385c. Epub 2011 Jul 20.

Abstract

We demonstrate a facile approach for converting AgCl to functional silver nanoparticles (AgNPs) via photoreduction in the presence of DNA. The resulting AgNPs are biofunctionalized, and exhibit photostable luminescence and DNA-specific Raman signatures, showing high potential for use in DNA-directed recognition and advanced bioimaging.
