ABSTRACT
In this chapter, the use of dielectric spectroscopy in the analysis of liquid disperse systems will be outlined. In particular, the analysis of pharmaceutical colloids and suspensions such as liposomes, microcapsules and emulsions will be described. Clearly, this represents a broad range of pharmaceutically important systems and only a brief outline of the uses and dielectric properties of each system may realistically be given. However, it is helpful to give an introduction to the definitions used here and the reasons why these systems are of such pharmaceutical importance.
