Patent ID: 6998637

Claim:
A circuit element having a first layer composed of an electrically insulating substrate material, comprising: a first electrically conductive material, which is in the form of at least one discrete area such that it is embedded in the substrate material and is applied to the substrate material; a second layer having a second electrically conductive material; and a monomolecular layer composed of redox-active bispyridinium molecules, which is arranged between the first layer composed of the electrically insulating substrate material and the second layer with the second electrically conductive material, with the bispyridinium molecules in the monomolecular layer being immobilized on the electrically conductive material which is in the form of at least one discrete area, and with bispyridinium molecules in the monomolecular layer making electrical contact with the second electrical material of the second layer, wherein electrically inert molecules are immobilized on the first layer which is composed of the electrically insulating substrate material, and which molecules form a matrix which surrounds the at least one discrete area with the monomolecular layer composed of bispyridinium molecules.
