Abstract
This paper proposes a concept of mechanical characterization of cell based on a new index which is measured by using the robot integrated microfluidic chip (robochip). We fabricate a pair of on-chip probe as the width tunable microchannel into the robochip, and the channel deform the target cell with periodic motion. When the vibration deformation is applied to the target cell, the cell start to move along the microchannel at a certain frequency due to the flow induced by the microchannel. We can regard the frequency as a index of the mechanical characteristics of stiffness of the cell.
