Lasers are the new DNA. It is called matrix-assisted laser desorption/ionization–time of flight (MALDI-TOF) and it uses mass spectrometry to quickly test for hundreds of different pathogens in a small sample using a single automated device. MALDI-TOF is increasingly being used in clinical micr... Read More
