a lipid-protein monolayer for a biosensor was prepared utilizing a langmuir-blodgett technique. the enzyme glucose oxidase was used as the protein. three types of lipid were chosen to change the surface charge of the polar group. the enzyme was immobilized on the lipid monolayer by adsorption from the subphase solution onto the lipid monolayer on the air/water interface. it was found that the lipid-enzyme interaction was dominated by electrostatic forces, and the characteristics of the film can be controlled by expansion and recompression of the adsorbed monolayer. finally, a glucose sensor was fabricated by depositing the film onto a hydrogen peroxide electrode
