| Research Abstract |
The purpose of this study is establish fundamental technologies of the micro driving system of fluid, which can be applied for the transportation devices in the micro-fluidics. The electro-magnetically spinning technique developed by us enables the remote manipulation of micro-mechanical elements, through the three dimensional control of the torque induced to the probe sphere. We successfully constructed an experimental system to deliver small probe sphere to an arbitrary position by driving the rolling motion of the probe. In addition by observing the relation between the driving torque and the motion of the probe, we succeeded in determining the local mechanical properties of the system. We found that the state of the solid-liquid interface is sensitive to the molecular adsorption and we are now extending the field of the system to the accurate detection of the chemical and biological functions.
