Bio-components from living body are very attractive nano-materials, because they have already achieved ultra-high and ultimate performance as the result of many cycles of natural selection and mutation. We first succeeded in obtaining the electron from the electron relay system in the inside of PSI by use of molecular wire as a connector, which was designed for facile electron transfer, and also demonstrated FET-operation using the electrons from PSI via. the molecular wire. This study has confirmed the validity of the novel approach and strategy to utilize bio-components as the core parts in an artificial system, which can be applied to many kinds of bio-functions.
