Abstract

Introduction: The global energy demand increases every year. So preparation of bio-fuel cells has been received much attention in recent years. BIOFUEL CELL is an energy conversion device which is used biological materials as catalysts. A BIOFUEL CELL might be applied to implantable medical devices and biosensors.Aim: The goal of this investigation is to explore new applications of carbon nanotubes as new materials in facilitating the DIRECT ELECTRON TRANSFER between biomolecules and electrode.Materials and Methods: GLUCOSE OXIDASE-based anode (Aspergillus niger) electrode of BIOFUEL CELL has been designed by using of multi-walled carbon nanotubes, due to the remarkable electronic and mechanical properties of multi-walled carbon nanotubes. In this study, the carbon electrode has been modified with the needlelike assembled multi-walled carbon nanotubes attached covalently to the carbon electrode and GLUCOSE OXIDASE attached to the multi-walled carbon nanotubes.Results: The linear rang of the bioanode to glucose concentration is from 10 mM up to 40 mM. By using this method, redox pick was achieved at 11 mA in 100 mM glucose containing solution.Conclusion: According to the results, presented method is more efficient than other methods with ensemble of multi-walled carbon nanotubes dispersed randomly on electrode surface to enhance DIRECT ELECTRON TRANSFER. Cyclic voltammetric results showed a pair of well-defined redox peaks, which corresponded to the DIRECT ELECTRON TRANSFER of GLUCOSE OXIDASE immobilized on needlelike assembled multi-walled carbon nanotubes, suggesting the method presented here may be used in GLUCOSE OXIDASE -based biosensors or as a bioanode in the BIOFUEL CELLs.
