Abstract
Disclosed is a composite of enzyme and carbon structure. In the composite of enzyme and carbon structure, a significantly large amount of an enzymeis immobilized on the surface of carbon structures without the formation of chemical bonds (particularly, covalent bonds) between the enzyme molecules and the carbon structures. Since the surface of the carbon structures does not need to be modified to form chemical bonds, the electrical conductivity of the composite of enzyme and carbon structure is not reduced and the stability of the composite is maintained high even after the passage of a long time in various environments. Therefore, the use of the composite of enzyme and carbon structure enables the fabrication of various devices, such as biosensors and biofuel cells, with markedly improved performance as compared to the use of conventional enzyme/carbon structure composites.
