Hydrogen bonding-induced color recovery of gold nanoparticles upon conjugation of amino acids

Chem Commun (Camb). 2009 Dec 21:(47):7354-6. doi: 10.1039/b918687e. Epub 2009 Nov 3.

Abstract

Hydrogen bonding-induced redispersion of the aggregated Au nanoparticles upon N-hydroxysuccinimide ester bioconjugations may provide a simple and colorimetric tool as an optical sensor to detect a trace amount of amino acids as low as approximately 10(-6) M in an aqueous solution.
