Aptamer-Studded Nanopore Detects Ricin

RNA lends sensitivity and specificity to sensor for potent bioterrorism agent
Department: Science & Technology
Keywords: nanopore, aptamer, ricin detection

A quantity of ricin smaller than a grain of sand can kill a person, so researchers are trying to develop sensitive detection methods for this potent bioterrorism threat. Now, Li-Qun Gu and colleagues at the University of Missouri, Columbia, report an aptamer-studded glass nanopore that detects single molecules of ricin protein (Anal. Chem., DOI: 10.1021/ac9006705).
