Adsorption of zwitterionic drugs on oxidized cellulose from aqueous solutions

Adsorption and inactivation behavior of horseradish peroxidase on cellulosic fiber surfaces

“…The accessible surface area is a function of the sorbate size. Although oxidation of the cellulosic fibers may result in different accessible surface areas for the enzyme, Zimnitsky et al [41] reported that the pore volume of the fibers increases considerably upon oxidation but the pore size distribution remains unchanged. Therefore, it could be assumed that the enzyme accesibility to the internal surface was not restricted in the case of the oxidized fibers.…”
