Caption
The graphic shows the experimental setup for performing evanescent scattering microscopy. The technique is a label-free method for sensitive imaging of biomolecules, including proteins. A beam of laser light is directed at a molecular sample with the proper angle to produce a condition known as total internal reflection. The resulting evanescent wave can excite the molecules at the glass-liquid interface, allowing for exceptionally precise imaging.
