A team of researchers have been working on a device that they claim can detect the presence of salmonella in food.
According to the team, the device is an “easy-to-use” colorimetric assay that is based on a novel nucleic acid probe, cleaved by an RNase enzyme specific to the salmonella species. The researchers have said that this specific enzymatic cleavage principle “made it possible to build a sensitive but simple and portable test system using colloidal gold”.
