Abstract

Technology for the attitudinal manipulation of medical equipment for local dosing to single living cells is presented. The authors developed a "juggling probe" which can manipulate a bacillary probe with multiple degrees of freedom and high accuracy without physical contact by using light pressure. With this technology, the authors cause two beams to focus on the probe from both the top and bottom faces. When the two focal points coincide, the probe becomes trapped immediately in a stable fixed attitude. Furthermore, the probe remains at rest in an arbitrary tilted attitude simply by controlling the distance between the two focal points.
