Dielectric Characterization of Leukocytes from Human Blood

The impedance spectroscopy technique was used to perform a comparative study on blood samples from leukemia and from healthy people. An electric circuit model was used to determine the numerical parameters of each sample. The capacitive properties, reflected in the constant phase element of a Cole model, show the capability to analyze the dielectric and spectral behavior of blood cells, in particular, with cells from leukemia. The spectra and the capacitive parameters are shown, as well as de model fitted to the experimental data.
