Abstract

Bead-shaped cellulose products and a process for the manufacturing of such ead-shaped porous cellulose products provide improved characteristics, particularly a hydrophilic, reversibly expandable cellulose matrix with a pore structure that can be adjusted within wide ranges in a targeted manner while non-specific mutual reactions are simultaneously suppressed by biomacromolecules.
