We have been developing optically driven nano-robot for measurement and manipulation of a single living cell. In this report, we have created a novel type of optically driven nano-robot for measuring biological proteins such as actin, myosin and so on. The new optically driven nano-robot is assembled two parallel beams extended from stiff base block with wall on each end. One of the beams can be bended to and fro by external laser. When target protens are clipped between two walls, the motion of the bended beam will be transferred by proteins to the other wall. By measuring movement of both walls, the nano-robot will identify mechanical characteristics of the proteins. This nano-robot becomes attractive device for cellular biological studies.
