Direct object resolution by image subtraction: a new molecular ruler for nanometric measurements on complexed fluorophores

Abstract

A technique for measuring distances between two or more fluorophores spaced in the 10–100 nm range is described. We identify a linear correlation between the intensity–amplitude in the difference-image of single molecules undergoing fluorescence fluctuations and their separation. The transform is used to map distances between coupled fluorophores.
