Mass photometry

Weighing molecules with light

A revolutionary new technology

Mass photometry is a revolutionary new method of analyzing molecules. It enables the accurate mass measurement of single molecules in solution, in their native state and without the need for labels.

This approach opens up new possibilities for bioanalytics and research into the functions of biomolecules.
