Researchers at Linköping University in Sweden have created electrical wires consisting of protein of ten nanometer fibers encased in plastic which are self-organised thin fibers and compatible with biological systems. These nano fibers are produced in ordinary test tubes using amyloid fibers, long, stable protein fibers that occur naturally in living organisms and a conjugated polymer (PEDOT-S), a plastic material that conducts current. When the two are mixed in water, the plastic attaches to the fibers and forms a conductive shell. By providing the fibers with charged outgrowths, it is possible to get the molecules themselves to form desired structures. This can be an inexpensive and effective way to create extremely tiny three-dimensional electronic circuits and also nano patterns in conductive plastic.
