Printable electric circuits, electronic components and method of forming the same

An electrical circuit having a plurality of passive components comprising:

• a substrate;
• a first seed layer positioned on the substrate in a selected pattern, the first seed layer having an affinity for a first preselected electrical material;
• a first electrical circuit component composed of the first preselected electrical material coupled to the substrate at the locations containing the seed layer and forming portions of the electrical circuit;
• a second seed layer positioned on the substrate, the second seed layer being positioned adjacent to the first seed layer at a plurality of locations on the substrate and having an upper surface with an affinity for a second preselected electrical material;
• a second electrical circuit component composed of the second preselected electrical material coupled to the substrate at the locations containing the second seed layer and being electrically coupled to the first electrical circuit component at those locations where the first and second seed layers are positioned adjacent to each other, the first and second electrical circuit components forming two different passive components in the electrical circuit, wherein the first seed layer is a first biomolecule and the second seed layer is a different, second biomolecule.
