Molecularly-imprinted polymer nanoparticles (NanoMIPs), fabricated using solid phase synthesis, were combined with electrochemical impedance spectroscopy (EIS) to develop an affinity sensor for cocaine detection. The nanosensor was able to identify cocaine at trace concentrations (~0.24 ng mL-1) with high specificity and discriminate it from both morphine and one of the most common cutting agents, levamisole. Overall, the sensor can provide onsite, fast, and accurate results and therefore can be considered a valid alternative to sniffer dogs and to the onsite screening methods currently in use to identify cocaine in environmental samples.View this paper.
