Abstract :
A glucose sensor was designed by immobilizing glucose oxidase (GOD) in a conducting organic Langmuir–Blodgett film (LB). GOD–LB complexes were characterized by infrared absorption. The rate of change in the dc conductivity for GOD–LB complexes is ranging from −13.4 to 7.9% after immersion in 3 × 10−2 mol/l glucose for 2 min. GOD possibly absorbs in the LB films and maintains its bioactivity and sensitivity. The present technique with highly ordered conducting LB films is to be used as a suitable platform for immobilization of the enzyme for sensor architecture.
