Bioelectronics is an emerging field, which extensively uses the supra-molecular structure of proteins, DNA etc to evolve products applicable in biosensors, switchable membranes, organic thin film transistors and fuel cells. This study shows that a partial purified metal-doped muscle protein from the fish, Clarius battracus, was fabricated with poly vinyl alcohol (PVA) to form a biopolymer thin film. The initial protein characterisation was done by gel electrophoresis, followed by analysing the thin film, using circular dichorism, fourier transformed infrared spectrum, scanning electron microscopy, electrical conductivity with and without temperature dependency and finally cyclic voltameter was used to study the architectures of donor and acceptor molecules. The study concludes that the metal-doped fish muscle protein and PVA gives rise to a conducting biopolymer, leading to a versatile molecular electronic material having a unique electrical and optical property, which could be used as a semiconductor in the arena of biochip, fuel cell and nanotechnology. @FootnoteText@ KEY WORDS: FISH, CONDUCTIVITY, METAL DOPING, PROTEIN.
