This review describes theoretical analysis and measurement techniques for dielectric spectroscopy of biological cells in the radio frequency range. The main focus is the beta-dispersion due to interfacial polarization. The beta-dispersion has been analyzed using various electrical models proposed for cells of diverse morphology. Recent technical developments in dielectric spectroscopy allow real-time monitoring of dynamic behavior of cells under physiological conditions and characterizing single cells.
