New Biosensor Can Detect Bacteria Instantaneously, Rovira i Virgili University Study
ScienceDaily (Sep. 8, 2009) — A research group from the Rovira i Virgili University (URV) in Tarragona has developed a biosensor that can immediately detect very low levels of Salmonella typhi, the bacteria that causes typhoid fever. The technique uses carbon nanotubes and synthetic DNA fragments that activate an electric signal when they link up with the pathogen.
