Abstract
The present invention relates to a biomemory device, comprising (a) a substrate; and (b) a heterolayer comprising a protein having a redox potential and an inorganic particle; wherein the heterolayer is immobilized on the substrate. By applying inorganic particles, the present invention provides a biomemory device capable of enhancing low current signals detected electron transfer between biomolecules and substrates up to at least five (5) times greater signals. The present invention is capable of controlling the redox states with help of redox potentials of proteins depending on applied potential. The present invention provides a new-concept biomemory device as an information storage device based on the principle of electron transfer of a naturally occurring biomolecule.
