Thin films based on melanin are prepared and characterized. The films display electrical conductivities comparable with amorphous silicon as well as a host of other interesting and potentially useful optoelectronic properties. The results may be useful for melanin‐based applications such as chemi‐sensors (in a variety of architectures including OFETS with chemi‐sensitive channels) and bolometric photon detectors.
