| Research Abstract |
A suspension of erythrocyte ghosts obtained by hypotonic hemolysis shows dielectric dispersion termedα-dispersion below 10 kHz. The exact nature of theα-dispersion, however, has not been studied because of difficulty in low-frequency measurement due to electrode polarization, and therefore its origin has not been clearly understood. In this study, a new electrode configuration was designed to extend the available frequency region to a lower frequency side, making it possible to investigate theα-dispersion in detail. The occurrence of theα-dispersion correlated strongly with the presence of holes in the ghost membranes and its properties were exactly interpreted by the numerical simulation with the spherical membrane model with a hole. The numerical simulation provided a liner relation between the characteristic frequency of theα-dispersion and the hole radius, and thereby the hole radius being determined straightforwardly.
