Towards a microrotary motor driven by motor proteins

Biological molecular motors, motor proteins, have a number of unique advantages over artificial motors, including efficient conversion of chemical energy into mechanical work and the potential for self-assembly into larger structures. This paper describes a biohybrid micro rotary motor using kinesin/ microtubule motor. We developed a simple fabrication process for a micro-structure by one-time deposition of parylene and a selective immobilization of protein molecules onto the specific region of its 3D microstructure. Using the parylene micro-rotor, we are challenging to make the micro motor, which smoothly and stably rotates by biological motor at least for few hours.
