1. A method to fabricate an electronic device on a substrate, comprising: genetically engineering first, second, third, and fourth viruses each having a plurality of selective binding sites; forming first, second, third, and fourth viral biotemplates by immersing the first, second, third, and fourth viruses in one or more solutions with nano materials coupleable to the binding sites of the viruses; self-assembling a gate with the first viral biotemplate having one site attachable to the substrate; self-assembling a source above the gate with the second viral biotemplate; self-assembling a channel with the third viral biotemplate having one site attachable to the second viral biotemplate; and self-assembling a drain with the fourth viral biotemplate having one site attachable to the third viral biotemplate.
