Abstract

A Non-Enzymatic glucose sensor was successfully developed based on platinum (Pt) particles immobilized on Pt electrode modified with polyaniline film (PANI) modified Pt electrode. The optimal conditions for maximum dispersion of Pt particles on PANI were evaluated. The Electrochemical behavior of the Pt/PANI/Pt sensor towards oxidation of glucose was studied in both alkaline (NaOH) and neutral (PBS) electrolytes using Cyclic Voltammetry and chronoamperometry techniques. The sensor showed a wide linear response to the glucose concentration from 0. 1 mM to 12 mM with linear regression coefficient of 0. 997. Furthermore, high sensitivity of 215. 8  A mM-1cm-2 is obtained with fast response time of less than 2 s. The as prepared sensor showed good stability, excellent reproducibility, and high selectivity to only glucose in presence of interferents. Finally, the applicability of the sensor was successfully verified with detection of glucose in juice samples. The results obtained were in good agreement with commercial glucose meter. These observations indicate that our sensor is promising in the field of non-enzyme based Glucose Sensors.
