The Investigation of Memory Functions of Biomolecular Device consisting of Metalloprotein |
| 초록 |
We demonstrated a protein-based memory device using recombinant Pseudomonas aeruginosa azurin (Azurin), a metalloprotein with a redox property. Azurin was recombined with a cysteine residue to enhance the stability of the self-assembled protein on the gold surface. The memory device characteristics, including the “Read”, “Write”, and “Erase” functions of the self-assembled azurin layer, were obtained with three distinct electrical states of azurin layers by cyclic voltammetry. It is concluded that the proposed device has a function of memory and can be used for the construction of nanoscale bioelectronic device with memory fuction.
