In order to enhance scientific knowledge and engineering capability in nano scale, it is crucial to develop manipulation tools, i.e. nano hands, for handling an individual nano object or molecule. The tool must be combined with an advanced characterization method having both single atomic or molecular level sensitivity and simultaneous imaging capability, i.e. nano eyes.
The author and his colleges have intensively investigated MEMS (micro electro mechanical system) design, fabrication and its application to nano and bio technologies. Nano scientific research using MEMS devices covers the tensile testing of nano contacts in transmission electron microscope (TEM) for in situ atomic level observation of deformation, micromachined Brownian motors and MEMS tweezers for capturing and characterizing DNA and other linear molecules electromechanically. MEMS for bio technology includes micromachined fL-chambers and heaters to allow single-molecular level enzymology , and the integration of bio molecular motors in MEMS for direct sorting and transportation of specific sample molecules. In this talk, I will focus on two topics; nano tensile testing in TEM and a nano transportation device driven by bio molecular motors.
