An Aptamer-Based Sensor For Small Molecules

Short strands of DNA enable a microfluidic sensor to detect cocaine in blood serum
Department: Science & Technology

Sensing small molecules in unprocessed aqueous solutions, such as blood and simple soil extracts, would be a boon for point-of-care medical diagnostics and environmental monitoring in the field. So far, however, such systems have been developed for only a few specialized targets. Now, scientists at the University of California, Santa Barbara, have developed a new microfluidic, electrochemical, aptamer-based sensor that has the potential to monitor many different targets (J. Am. Chem. Soc., DOI: "; $("#ERA_RC").html(contextualDefault); } }); var era_rc1 = {StyleId: '1',ERADomain: 'cen.firstlightera.com'};
