Abstract

A Neuropeptide Y-binding aptamer (NPY-BA) and 15 nm gold nanoparticles (AuNPs) were used to create plasmonic aptasensors for the selective detection of Neuropeptide Y in a rapid colorimetric assay. In this report, we describe different parameters that can be varied to optimize the sensitivity and selectivity of these assay and demonstrate initial NPY detection in sweat.
