Abstract

Complex numbers: The number of molecules detected in the evanescent field during single-molecule fluorescence imaging decreases with increasing molecular weight in free solution (see graphic; FITC = fluorescein isothiocyanate). This technique could be useful for screening undefined molecular interactions at extremely low concentrations without separation.
