Data obtained by this technique allow rather detailed conclusions about the location of the solubilizate in the aggregate. Fluorescence quenching rate constants vary with temperature, local microviscosity and quencher concentration. Encapsulation of spin probes has been examined in detail by EPR spectroscopy. ...
