Fluorescence fluctuation spectroscopy in reduced detection volumes.
Fluorescence fluctuation spectroscopy is a versatile technique applied to in vitro and in vivo investigations of biochemical processes such as interactions, mobilities or densities with high specifity and sensitivity. The prerequisite of this dynamical fluorescence technique is to have, at a time, only few fluorescent molecules in the detection volume in order to generate significant fluorescence fluctuations. For usual confocal fluorescence microscopy this amounts to a useful concentration i...Expand abstract
