Microscale thermophoresis (MST) is a biophysical technique used to measure the binding interaction between molecules. There are various synonyms for MST, such as nanothermal analysis, nanothermometry, nanocalorimetry, and thermophoretic analysis. All these terms describe the same technique, which uses an infrared laser to measure the temperature gradient around two molecules as they bind or dissociate. MST is a highly precise and sensitive method that can analyze molecular interactions across a wide range of concentrations and conditions, making it an invaluable tool in drug discovery, biomarker identification, and fundamental biochemical research. Thus, knowing these synonyms will help researchers to communicate their findings and collaborate with others in the field.
