Abstract
Organic light-emitting diodes are disclosed comprising an electron transport layer and a hole transport layer. At least one of the transport layers is formed by (a) dissolving tubulin or microtubules in a mixture of water and a solvent that changes the surface charge of tubulin, wherein the percentage of solvent in the mixture is selected so that the tubulin acquires a desired surface charge, and (b) using the tubulin with the desired surface charge to fabricate the at least one of the transport layers. Advantageously, the solvent may be DMSO. Methods of fabricating such organic light emitting diodes are also disclosed.
