This paper reports the releasing method for micro manipulation utilizing manipulator. In micro-scale, since surface forces such as adsorption force is greater than body forces such as gravitational force, adhesion force between the end-effector and the object is strong. Therefore in the case of micromanipulation utilizing manipulator, to set the object to an arbitrary place, manipulation techniques without adhesion are required. In this time, to decrease adhesion force, manipulators with nanostructured surface were fabricated. And cell manipulation experiments using mouse fibroblast cells were conducted. When a manipulator with nanostructured surface was used, releasing without adhesion was successful 85.0% of the time. On the other hand, when a manipulator without nanostructured surface was used, releasing without adhesion was successful 6.3% of the time. As the results, high accuracy cell manipulation without adhesion was performed successfully.
