◆Research Interests
Micro-Mechanical Devices Powered by Motor Proteins
Living organisms have developed diverse functions through evolution over a long period of time. Some functions are related to mobility, including muscle contraction, bacteria' s swimming and cell division. Nanometer proteins called motor proteins are integrated into motion assemblies with dimensions ranging from the micrometer-scale (bacteria) to the meter-scale (muscle). A motor protein is a molecular machine that converts chemical energy into dynamic force with great efficiency. This is an excellent property that conventional artificial motors do not have. In our laboratory, we are developing biohybrid micromachines using organic motors and micro-fabrication technology. 備考
