Patent ID: 7615369

Claim:
An electrode system for protein patterning, the electrode comprising: a first electrode containing structure comprising a patterned conductive layer; a non-adherent layer disposed over the patterned conductive layer, the non-adherent layer having a non-adherent surface that is hydrophobic and non-polar; a second electrode containing structure disposed over the non-adherent layer; and a power supply in communication with the first electrode containing structure and the second electrode containing structure, wherein the first electrode containing structure, the non-adherent layer, and the second electrode containing structure are positioned relative to each other to allow contacting of the non-adherent layer with a protein composition in a solution; and wherein the non-adherent layer is capable of acquiring an electric charge or of being polarized such that application of a potential difference between the first electrode containing structure and the second electrode containing structure renders the non-adherent layer adherent to protein molecules in the solution until the potential difference between the first electrode containing structure and the second electrode containing structure is reversed.
