With Electrokinetic Spectroscopy we refer to the Electrokinetic techniques whose frequency response shows a very rich behavior, providing a vast amount of information partially hidden in their DC counterparts. Of particular interest for the present Research Topic are those techniques aimed at the evaluation of the physico-chemical properties of the involved surfaces, such as surface charge and potential, chemical composition, polarization state, geometry, etc.
The considered systems include any type of colloid, but special emphasis should be put on complex surfaces or suspensions, such as those including soft, non-spherical or Janus particles, and those where interactions are strong, such as concentrated or salt-free systems. Biological systems such as DNA and cells are also considered in the Research Topic.
Among the techniques suitable for those purposes we focus on the determination of dynamic electrophoretic mobility, low frequency dielectric dispersion, electric birefringence and dielectrophoresis. The information obtained from these spectroscopic studies is very useful not only for the characterization of the considered systems, but also for other applications like electro-rheology or the recently expanding interest on the versatile micro-manipulation that electric fields can provide.
