“…The elucidation of the internal structure of microemulsions, although important, can be very complex, therefore sophisticated physical techniques are required for this purpose, e.g., dynamic light scattering (DLS) [21], electron microscopy [22], EPR spectroscopy [23], or time resolved fluorescence quenching (TRFQ) [24]. Other methods, i.e., conductance [15,25], viscosity [21], infrared spectroscopy [26], UV-vis spectroscopy [27], small angle neutron scattering (SANS) [28] may play supportive role for the multiphase system characteristics. By comparing different experimental methods it is possible to determine the type and internal structure of the microemulsion [29,30].…”
