Studies on the Lipase Monolayer Film Self-assembly on the Nagatively Charged Poly(ethylene terephthalate) Substrate

Abstract

Abstract: The PET-CO₂^- film was prepared and the lipase was assembled on the surface of the PET CO₂^- substrate. The structure of the surface and activity of lipase/PETmonolayer were studied by FTIR-ATRand AFMand other methods. As shown in the results, AFMimages of lipase/PETmonolayer indicated that the surface fluctuation is in the range of nanometer scale and the depth of monolayer is less than 15 nanometers. The performance activity of lipase/PETmonolayer self assembly film is above 2.0.

Key words: Lipase monolayer, Molecular self assembly, Poly(ethylene terephthalate), AFM, FTIR-ATR
