Conducting polymers have attracted considerable attention in many research fields owing to their overwhelming characteristics like ease of processability, ability of conduct electricity, low cost, straight forward preparation techniques. Our research interests are conducting polymer based electrochromic devices, solar cells, organic light emitting diodes and biosensors. The biosensor technology has attracted great interest due to its many important applications. The new developed techniques also have advantages over conventional laboratory based assays. The conventional methods are time consuming, expensive, required well trained personnel and not used for real time measurements. Nevertheless, biosensors are inexpensive, portable with minimized design, easy to handle, selective and sensitive.  In our group, a wide variety of biosensors were emerged as conducting polymer based enzyme biosensors. For these purposes, many conducting polymers which have specific groups were designed and synthesized. These polymers were utilized as immobilization matrices for biosensor construction. During immobilization, several modification structures were used in biosensor fabrication to achieve the most effective surface design for target biosensors. By applying constant potential, consumption of oxygen concentration in bulk solution was followed using amperometric technique. Surface features of the biosensors were characterized using several techniques like SEM, XPS, TEM, and Fluorescence Microscopy. Also, kinetic parameters, operational and storage stabilities were determined. Then, the fabricated biosensors were tested for the detection of target analytes. The result of the biosensor agreed very well with reference methods
