Abstract

The detection of cocaine based on an aptamer-modified molybdenum disulfide@gold nanoparticle (MoS2@AuNP) nanosheet array immobilized on aminated slides was achieved. Cocaine was detected using fluorescence energy resonance transfer between MoS2@AuNPs and an aptamer modified with Cy5. The method had a detection limit of 0.19388 nM for cocaine.
