Carbon Nanofiber-Based Glucose Biosensor

Abstract

The use of highly activated carbon nanofibers for the\ndesign of catalytic electrochemical biosensors is demonstrated. The direct immobilization of enzymes onto the\nsurface of carbon nanofibers is shown to be a highly\nefficient method for the development of a new class of very\nsensitive, stable, and reproducible electrochemical biosensors. These results establish the fact that the carbon\nnanofiber is the best matrix so far described for the\ndevelopment of biosensors, far superior to carbon nanotubes or graphite powder.
