ABSTRACT
Dielectric spectroscopy is a powerful tool for studying all kinds of colloidal suspensions: macromolecules [1-5], micelles [6-8], latex [9-18], lyposomes [19], and cells [20-27]. Among these systems, polystyrene particles and cell suspensions stand out as being the simplest, which still exhibit all the main relaxations. This makes them ideal study subjects for analyzing the response of colloidal suspensions to an applied electric field. Such an analysis constitutes the purpose of this work.
