Abstract :
We have developed an on-chip untetherd robot, which has suction mechanism. The robot has a pump activated by a permanent magnet and an electrical magnet. The robot is manipulated and positioned by permanent magnets. We established the fabrication process of the nano-pipette on the robot by using negative-photoresist sheet to make hollow structure. We performed the experiment of manipulation of bovine oocyte with the robot, and loading of a bovine oocyte from cell chamber to micro-channel.
