Abstract
The dynamic organization of a mixed Langmuir film of glucose oxidase a nd behenic acid has been studied. Samples of the mixed film transferre d after different relaxation times were analyzed by UV-Vis and IR spec troscopies and by lateral force microscopy. The results demonstrate th at the enzyme molecules present at the air/water interface are progres sively covered by the behenic acid film. Moreover, we observe an incre ase of the quantity of glucose oxidase in the mixed film with time, sh owing that the adsorption of glucose oxidase under the behenic acid fi lm continues during and after the relaxation process.
