초록/요약
The self-assembly layer consisting of fusion protein is investigated in molecular-scale for the construction of bioelectronic device.Cytochromeb562 and green uorescent protein were used as an electron acceptor and a sensitizer in the molecular layer by mim-icking the photosynthesis. Self-assembled monolayer of fusion protein was formed on Au coated glass. The formation of fusion pro-tein layer onto the Au substrate was observed by the surface plasmon resonance measurement. The surface of fusion protein layerwas observed and analyzed by the scanning tunneling microscopy observation. For embodiment of the molecular electronic device,molecular arrays of fusion protein SA layer were formed by micro contact printing. Surface charge distribution of fusion protein SAlayer was measured to conrm an electrical conductivity by electrostatic force microscopy observation.
