Abstract

A method is presented to characterize the molecular weight distribution of a polymer composed of fluorescent monomers in solution. This method. which the authors call 'Fluorescence Distribution Spectroscopy' (FDS), measures the amplitude of fluctuations of the total number of polymer subunits in a well defined small open volume. The number of subunits is measured in terms of the total fluorescence emission from a volume defined by a laser beam. This method does not perturb the measured system and therefore has the advantage being applicable to labile or reversible polymerization or aggregation systems and therefore should be particularly useful in biological studies.
