Among the various biological cells, the Red Blood cells are readily obtained in large quantities and least understood interms of their physiology. In view of this, an attempt has been made to study the dielectric properties of fish and Human erythrocytes using the technique of Dielectrophoresis. The present study reports the data on the Dielectrophoretic Collection Rate (DCR) and Threshold Voltage (VTh) of fish and Human erythrocytes. In this study, Erythrocyte suspension of fish and Humans is subjected to a Non-Uniform Electric field produced by Pin-Pin electrode configuration. The parameters DCR and VThare measured at constant voltage, frequency, and cell concentration. The study reveals a significant difference in the values of DCR and VThof fish Erythrocytes when compared with that of Human Erythrocytes.
However special importance is given in the present study regarding the application of the Dielectrophoretic technique in fisheries research. This technique offers a fruitful method for learning the cellular as well as electrical makeup of biological cells.
