Conducting polymer based nano-biosensors has become more feasible and cost effective alternative for conventional biosensors. Sensitivity and linear range have been improved in last couple of years. Since the effective surface area in nano-scale has a direct influence on the amount of enzyme loaded onto the biosensor, it was tried to increase the effective surface area of the polypyrrole substrate film using a unique technique. This paper describes the outcomes of the novel technique.Electro deposition of polypyrrole under a constant current is a common practice in order to fabricate a conducting polymer substrate for nano-biosensors. However, the results in Figure 1 show that the pulsed deposition of polypyrolle make a nano-structured surface.
