Cross-Reactive Plasmonic Aptasensors for Controlled Substance Identification

Cross-Reactive Plasmonic Aptasensors for Controlled Substance Identification

In this work, we developed an assay to determine if an arbitrary white powder is a controlled substance, given the plasmonic response of aptamer-gold nanoparticle conjugates (Apt-AuNPs). Toward this end, we designed Apt-AuNPs with specific a response to common controlled substances without cross rea...
