Abstract: Adsorbed layers of glucose oxidase on the air/water interface were prepared and investigated. The transfer of one to ten lipid-protein monolayers onto Pt-electrodes under 20–40 mN/m surface pressure by Langmuir – Blodgett method was performed to yield a biosensor with a measuring range of 0,5–5,0 mM glucose. The amperometric response of the biosensor to glucose depends on the number of the transferred lipid-protein mono-layers and on the surface pressure in the course of the transfer.
