Patent ID: 7917296

Claim:
A biomolecular electronic switch that can be switched from a first to a second state by the application of a current, and can be returned to its first state by the absence of a current, comprising: a first electrical contact comprising a substantially pure aluminum electrode 40-100 Å thick; a layer of electrode selected from the group of titanium or platinum, 30-80 Å thick, directly under the substantially pure aluminum electrode; a monolayer of cyctochrome c 40 Å thick directly under the layer of electrode selected from the group of titanium or platinum; a layer of aluminum oxide electrode 30-80 Å thick, directly under the monolayer of cyctochrome c; a layer of substantially pure aluminum electrode 50-100 Å thick, directly under the layer of aluminum oxide; a layer of silicon dioxide directly under the aluminum electrode; and a layer of silicon substrate.
