Matrix-assisted Laser Desorption Ionization Time-of-flight Mass Spectrometry
Matrix-assisted Laser Desorption Ionization Time-of-flight Mass Spectrometry (MALDI-TOF MS) is a technique frequently used in analytical chemistry for the identification and characterisation of molecules. It works by monitoring the differences in the time that molecules of different mass take to fly through an electric field, enabling them to be separated and identified. This technique is important in many areas of research as it is an extremely sensitive and fast method for determining the molecular weight of a compound. It is used to identify and quantify individual proteins, lipids, carbohydrates, and other small organic molecules, and is also used to study interactions between molecules. In addition, MALDI-TOF MS is a useful tool for medical diagnostics, allowing the identification of bacteria and viruses, as well as enabling the monitoring of drug concentration in the blood.
