    Preparation of electro-active polymers having characteristic surface on biological tissue was carried out. Direct polymerisation on biological material with unique structure can be a new method to obtain functional structure with no use of top-down or bottom-up technologies. Polymerisations of pyrrole, aniline, and 3,4-ethylenedioxythiophene (EDOT) were carried out on the bio-tissues. Surface structure of the bio-tissue/conducting polymer composite was observed with optical microscopy. The results of the present study involve demonstration of deposition of conducting polymers on the surface of wood, membrane of egg, fungus, flower, and bacteria in the water medium. This method allows preparation of electro-active composites with ordered structure through combination of structures of biological tissues. Note that electrochemical polymerisation in bacterial electrolyte solution can be a first example to date.
