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.
