Characterization of biosurfactants' micelles formation using fluorescence measurements: sodium taurocholate as case of study.

Background And Purpose: The evaluation of micellization parameters of surfactants that aggregate gradually, such as bile salts, is not trivial. In this work, different probes and data treatment models are tested to set up an analytical method based on fluorescence measurements to determine the critical micelle concentration (CMC) and micellization range (() of biosurfactants. Sodium taurocholate (NaTc) is used as example.
