Microcrystalline cellulose has been oxidized employing the newly reported N-hydroxyphthalimide-cerium ammonium nitrate system, at alkaline pH using sodium hypochlorite and sodium bromide in water, after an ultrasonication treatment. The water-soluble oxidized cellulose fraction (OCws) thus obtained has been analyzed by Fourier transform infrared and 13C NMR and used subsequently for adsorption onto aminolyzed poly(ethylene terephthalate) films deposited onto sensors of a quartz crystal microbalance with dissipation detection (QCM-D). The successful immobilization was monitored using QCM-D, and the morphology of the films was studied by means of atomic force microscopy.
