A novel DNA-based biomemory device that was comprised of self-assembled monolayers (SAM) of ssDNA/Cu heterolayers on Au electrodes was fabricated for making biomemory device. A thiol-modified single strand DNA (26 bp) was designed and immobilized on the Au electrode. The film fabrication was confirmed by surface plasmon resornance (SPR) spectroscopy and Raman spectroscopy. The redox properties of the ssDNA/Cu molecules were measured though cyclic voltammetry (CV) experiments and open circuit potential to assign the memory parameters. The open circuit potential amperometry (OCPA) provides a various memory function using these three assigned parameters. This novel DNA-based memory device gives the new-type memory system for new biochip technologies.
