Portable Electrochemical Cocaine Biosensor

Chemists crack cocaine detection. ‘Researchers, including two high school students and a Nobel laureate, have created a sensitive, easy to use device to detect cocaine and other small molecules. The team, led by Kevin Plaxco at the University of California at Santa Barbara, US, developed a small molecule sensor based on aptamer technology. Aptamers are DNA strands designed to recognise specific molecules. The technology was coupled with an electrochemical system that translated the molecular recognition event into an electrical signal.’
