Unmodified gold nanoparticles as a colorimetric probe for potassium DNA aptamers

Chem Commun (Camb). 2006 Sep 28:(36):3780-2. doi: 10.1039/b607448k. Epub 2006 Aug 8.

Abstract

Unmodified gold nanoparticles effectively differentiate unfolded and folded DNA, thus providing a novel approach to colorimetrically probe aptamer-based recognition processes.
