Abstract
This paper discusses the evaluation of cell mechanical impedance by using a μ-channel. Through experiments, we found that the velocity profile of a red blood cell passing through a μ-channel can be separated into two phases; one is in the entrance area of the channel where the velocity heavily changes, and the other is in the remaining area where the velocity is almost constant. By focusing on the area of constant velocity, the stiffness effect can be evaluated, while the viscosity can be evaluated by focusing on the cell behavior in the entrance area. In this report, we show experimental data under two different initial speeds of cells, and consider the effect of impedance precisely.
