The Time-Resolved Fluorescence Quenching Method for the Study of Micellar Systems and Microemulsions : Principle and Limitations of the Method

Abstract

ABSTRACf. The application of time-resolved fluorescence quenching method to the determination of the size of micelles and oil-in-water or water-in-oil microdroplets is described. It is also shown that this method gives information on dynamic processes occurring in micellar solutions and microemulsions. In this account the scope and limitations of the method are discussed with special emphasis placed on the assumptions used to interpret the fluorescence decay data and on the selection of appropriate probe and quencher molecules. Recent developments are also briefly presented.
