Molecular Robotics and Molecular Computing by nanobiotechnology

We are challenging to construct autonomous nano/micrometer-sized “molecular robots” and “molecular computers”. Molecular robots and molecular computers are made of biopolymers and biomaterials such as DNA, protein, lipids, etc. The Molecular robots and molecular computers have autonomously working sensors, processors, and actuators. They can work in microscopic spaces like inside of cells and can be applied to medical systems, tiny machines, etc. See the following reviews and our published papers for detail:

Artificial Cell and Nonlinear Non-equilibrium Science with Microfluidics

We are constructing “artificial cells” using biomolecules (DNA, RNA, protein, lipid, etc.) to understand essential aspect of life systems. Life systems exhibit dynamical behavior such as autonomous sensing, autonomous information processing, autonomous motion, etc. Artificially constructing cell-like systems is important not only for basic science (physics, chemistry, biology) but also for applied science and engineering.
