Rapid Visual Detection of Pathogen Nucleic Acids
November 27, 2018 | Terry Sharrer
A*STAR scientists in Singapore have developed a pathogen DNA system that has visible detection—a system called “enVision” for enzyme-assisted nanocomplexes for visual identification of nucleic acids. They report: “The system consists of an integrated circuit of enzyme–DNA nanostructures, which function as independent recognition and signaling elements, for direct and versatile detection of pathogen nucleic acids from infected cells. The built-in enzymatic cascades produce a rapid color readout for the naked eye; the assay is thus fast (<2 h), sensitive (<10 amol), and readily quantified with smartphones.” MORE
