We are interested in how living bodies move. The ways they move are significantly different from those of artificial ones. We have succeeded to observe the movement of a single filament of biological motor proteins in aqueous solutions. The filaments move as if they are living (!) even though they are just a sort of proteins. To understand the detailed mechanism of their motion should be a key to understand the life itself. Recently, we have combined distinguishing characters of motor proteins to an electric large-scale integrated circuit (LSI) to make novel bio-devices. The devices could work in a femto liter volume level (10x10-15 ℓ) and be useful to monitor the mental conditions in our everyday life.

1. Understanding molecular mechanisms of biological motility
2. Development of bio-devices fusing motor proteins and LSI
