Electroactive luminescent bio‐organic nanowires , 10 nm in width and with lengths up to 10 μm (see Figure), are generated through co‐assembly of protein amyloid fibrils with conjugated oligoelectrolytes. The electro‐optical properties of the wires are demonstrated with reversible electrochemical doping‐induced fluorescence quenching, providing evidence for both electrical transport and electroactivity.
