Electrochemically Synthesized Polypyrrole Nanofibers Towards Glucose Biosensing Application
In this paper, we have reported an enzymatic glucose biosensor utilizing para-Toluenesulfonic acid (p-TSA) doped Polypyrrole nanofiber array (PNA) as a support matrix for enzyme immobilization. PNA doped with varying concentrations of p-TSA was synthesized electrochemically over Platinum coated glass substrate for the same. The influence of different concentrations of p-TSA on PNA morphology and thus its effect on glucose biosensing has been observed. The fabricated glucose biosensor has shown the maximum sensitivity corresponding to 20 mM p-TSA doped polypyrrole support matrix.
