Biological sensors, electrically active polymers

Other applications of conductive polymers in chemical and biological sensors include a building of electrical connection between different elements of these devices6 or electrical connection and mediators of electron transfer between enzyme and electrode26,27 or between electrocatalytically active functional groups or incorporated nanoparticles and electrode,28 as a filter,29 as matrix for immobilization of enzymes or even as a combination of many of these functions.26 The requirements for materials for these applications are very specific and will not be analyzed here.
