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

Jin-Ho Park, Erdene Ochir Ganbold, Dembereldorj Uuriintuya, Kangtaek Lee and Sang-Woo Joo

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 10-6 M in an aqueous solution.
