Free and confined water at the erythrocyte membranes of healthy and invalid individuals: a microwave dielectric study

Abstract

Blood is a concentrated suspension of red blood cells (RBC) and its dielectric parameters are of relevance for medical diagnostics and other medical applications. As it was shown the values of permittivity of diluted suspensions of RBC and RBC ghosts of the blood sampled from patients with different types of cancer have been measurement in the patients before and after X-ray treatment. The proposed mechanism of the dielectric changes is based on the disease-specific modifications of the RBC membranes.
