Aptamer-Studded Nanopore Detects Ricin
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). The team attached copies . . .
