We propose a novel type of optically controlled micromanipulation tools that can work in sealed micro space. The micromanipulator arm has a handle to rotate the arm on its long axis. When a focused laser beam is focused on the handle and scanned linearly in the focal plane, the handle is inclined toward the focus. As a result, the arm is rotated on its long axis. The rolling mechanism allows us to manipulate a microobject stably. The micromanipulators with the rolling mechanism were fabricated by using high-speed two-photon microstereolithography. We demonstrated that the manipulators could catch a microparticle in three-dimensions. In addition, a single manipulator arm was successfully used for sliding a microparticle on a cover glass. Such optically controlled micromanipulators offer versatile and powerful tools for micro total analysis systems for biological applications.
