A group of researchers to simplify and accelerate the identification of products contaminated with Salmonella have developed a microfluidic disk. The original device is able to detect DNA of pathogens, less than half an hour.Standard methods of determining food-borne pathogens suggest a crop that takes one day. South Korean scientists from the national Institute of science and technology has proposed a new, quick and easy test. Although there are bole fast ways to detect Salmonella, however, they require expensive equipment and qualified personnel.The new method uses a microfluidic chip, similar to a music CD. Through laser and rotation is the study of the DNA sample.
