AbstractWe fabricated the proein-based biomemory device by an introduction of the cytochrome c. The cytochrome c is an iron storage protein of organisms and has redox property. 11- mercaptoundecanoic acid was used as a linker material to immobilize the cytochrome c on the Au substrates. The immoibilized surface was confirmed by surface plasmon resonance spectroscopy. And the surface topography of cytochrome c layer on Au surface was investigated by scanning tunneling microscopy. The redox property of cytochrome c molecules immobilized onto Au surface using chemical linker was demonstrated by using cyclic voltammetry technique. The fabricated memory device shows the two type of memory characteristics well. Its memory effects were determined by using the chronoamperometry and open circuit potential amperometry. In these results, it could be concluded that the cytochrome c layer could be used for the construction of nanobiochip with memory function.
