Abstract

We succeeded in cell positioning with 1 [μm] resolution under the best tuning and with the maximum speed of 12 [cells/sec], by utilizing a PDMS chip including the micro channel whose diameter is slightly less than the cell to be handled. The key idea is that cell motion with originally six degrees of freedom (d.o.f) in free space is constrained to one d.o.f by pushing cell into a channel. Focusing on the positioning of cell in the micro channel, we also confirmed that the position control is stable due to enough viscous force between cell and wall of the channel.
