Current bioanalytical techniques often employ binding, labeling, or separation methods to measure molecular mass, molecular interactions, and structural integrity, but these methods can alter the native state of the molecule, leading to inaccurate or incomplete characterization.

At Refeyn, we are challenging the status quo by leveraging the unique properties of mass photometry to directly measure molecular mass at the single molecule level in solution without the use of labels, simplifying sample preparation and capturing true molecular behaviour dynamics in a native, aqueous environment.
