Mass Photometry, Oxford, United Kingdom

Mass Photometry is an interferometric microscopy technique which allows single molecule mass measurement of biological molecules (proteins, DNA, antibodies, etc) by detecting minute changes in the reflected light caused by changes in dielectric constant of the medium as the molecule approaches and binds to a surface. The method has myriad applications to biophysical systems, ranging from rapid in lab mass measurements to tracking single molecules moving across a substrate.
