Bridging bio to nano : A simple procedure is reported to fabricate a biosensor by using the capacities of pyrene derivatives which are attached to nanotube sidewalls and to form host–guest complexes with β‐cyclodextrins (see figure). A trisbipy iron(II) complex containing six pyrene groups was synthesized and attached to carbon nanotubes. β‐Cyclodextrin‐modified glucose oxidase was used as a model enzyme to form the pyrene/β‐cyclodextrin inclusion complex, thus efficiently immobilizing the enzyme.
