Highly uniform indicator-mediated SERS sensor platform for the detection of Zn2+†
Abstract
An indicator-mediated surface-enhanced Raman scattering sensor platform with highly uniform SERS sensitivity was fabricated by modifying 4-mercaptopyridine molecules onto the surface of Ag nanoparticles that were anchored onto a silicon wafer. The present SERS sensor platform realized quantitative detection of Zn2+.
