Outline of Final Research Achievements

In this research, we are developing a technology for enabling remote and parallel manipulation of biological molecules in water by utilzing spatially localized induction of electrostatic fields in a nanofluidic space. We have developed a simple method of fabricating a device that has a nanofluidic channel with withdth of 50-200um and with thickness smaller than 100nm, which is smaller than thickness of the electric double layer. Moreover, we developed an optical and electrical setup for projecting arbitrary optical illumination and demonstrated the optoelectric manipulation of small particles.
