Study on Dielectrophoresis and Electrorotation of Malaria Infected Cells

Abstract

This paper presents the study of dielectrophoretic and electrorotating responses of red blood cells with varied electric field frequency. Normal red blood cells and Plasmodium Falciparum infected-cells were used in the experiments under extracellular conductivity of 0.02 S/m. The results showed that the difference in electrical properties for the normal and infected cells making change in the aforementioned responses. The infected cells had higher intracellular conductivity by 46% and lower specific membrane capacitance by 50% than the normal cells approximately. This difference can be applied to the disease diagnosis.
