This is MALDI-TOF in action, and yes, it sounds as satisfying as it looks. MALDI-TOF stands for Matrix Assisted Laser Desorption Ionization Time of Flight, and in simple terms, it’s a machine that identifies bacteria by analyzing their protein “fingerprint.” Instead of waiting days for biochemical tests, we can get an organism’s identity in minutes. The principle is actually pretty elegant. A laser hits the sample, ionizes the proteins, and sends them flying through a vacuum tube. The time it ta
