Nanofibers Used in Production of Glucose Electrochemical Sensors

Tehran, Iran | Posted on December 31st, 2012

The study was carried out by Iranian researchers from Islamic Azad University, Khorram Abad branch, and Razi University of Kermanshah.

The produced electrode is sustainable and it has very high resistance during electrochemical reactions. Therefore, it can be a very appropriate option in various analytical purposes.

Enzyme-free electrochemical methods are preferred due to their stability, simplicity, sustainability, and reasonable price in comparison to other glucose detection methods. Taking into consideration the chemical properties of pyromellitic acid such as flexibility and the ability to form hydrogen bond, the researchers produced a stable modified electrode for the electrocatalytic oxidation of glucose by electrolyte deposition of pyromellitic acid - nickel composition on the surface of Au-Pt nanocomposite glass carbon electrode in an alkaline solution.

Some reaction parameters, including electron transfer coefficient, glucose diffusion coefficient, and catalytic reaction rate constant were calculated during the research. Results showed that the pyromellitic acid - nickel film stabilized on the nanocomposite electrode had a very good catalytic activity against the glucose oxidation. In addition, the reactivity of the electrode against the current was much better than other electrodes due to the combination of a metallic nanofiber and carbon nanotube.

Considering the obtained results, it was found out that the presence of nanofibers in the modified electrode not only stabilized the single-metallic particles, but also brought advantages such as the single step of the preparation method, very homogenous distribution of nanometric particles, and the diversity in the matrix formation in form of sol-gel film and monolyte.

Results of the research have been published in August 2012 in Electrochimica Acta, vol. 76, pp. 300-311.
