  • Title: Nanoplasmonic detection of adenosine triphosphate by aptamer regulated self-catalytic growth of single gold nanoparticles.
    Author: Liu Q, Jing C, Zheng X, Gu Z, Li D, Li DW, Huang Q, Long YT, Fan C.
    Journal: Chem Commun (Camb); 2012 Oct 07; 48(77):9574-6. PubMed ID: 22871726.
    Abstract:
    We present a nanoplasmonic aptasensor for adenosine triphosphate (ATP) by using single gold nanoparticles (GNPs) as probes. The specific aptamer-ATP binding induced conformational change could modulate the surface-dependent self-catalytic growth of GNPs, which enabled the detection of ATP with ultra-sensitivity and selectivity.
