Conductivity of Normal and Pathological Human Erythrocytes (Homozygous β-Thalassemia) at Radiowave Frequencies

Abstract

Abstract The conductivity of normal and homozygous β-thalassemic erythrocyte suspensions has been measured over the frequency range from 5 KHz to 100 MHz in the temperature interval from 5 to 45 °C. The electrical parameters of the membrane, i.e., the capacitance CM and the conductance GM per unit surface have been calculated from an expression given by Hanai for the conductivity of a suspension of ellipsoidal particles covered with a shell. Some interesting differences between the normal and pathological state are evidentiated.
