Abstract
Detecting single molecules includes binding the single molecules to a surface of an optically transparent substrate, irradiating the surface of the substrate with light having an incident angle selected to achieve total reflection of the light, thereby scattering light from the surface and from the single molecules bound to the surface, and collecting light scatted by the surface and by the single molecules bound to the surface to form a series of images. Systems for detecting single molecules include an optically transparent substrate, a means for flowing a sample solution over a surface of the substrate, a light source configured to irradiate the surface, a camera, and a collection optical system configured to collect light scatted by the surface and by the target molecules on the surface to form a series of images on the camera.
