Mass photometry is a recent addition to the bioanalytical toolkit. By directly measuring molecular mass in solution, it reports on fundamental properties of the sample while a native environment is maintained. It is thus applicable to a wide range of different molecules and to both basic research and drug discovery. 

Mass photometry measures mass at the single molecule level, providing insights into the composition and function of even complex samples and molecular mechanisms. This unique technology can detect and characterise proteins, nucleic acids, lipids and sugars. It provides information on structure (oligomeric state, modification), homogeneity, and function (quantifying interactions) – all in a matter of minutes and using tiny amounts of sample.

Due to its unique benefits, mass photometry addresses  a major unmet need for more efficient analytical tools. It will ultimately help accelerate science, and the discovery and development of new therapeutics.
