Figure 7. Nanostructured materials used in glucose sensors. Currently applied electrochemical glucose sensors (left) use glucose oxidase (GOx) to generate an electrochemical signal. This signal is transferred through O₂ reduction into H₂O₂ (or some other chemical mediator). Nanomaterials, as nanotubes or nanocomposites, are incorporated into such sensors (right) aiming to increase the surface area, improve catalytic efficacy, modify operating parameters, and improve the electron transfer from enzyme to electrode (adapted from [2])
