Cellulose as a (bio)affinity carrier: properties, design and applications.

This contribution presents a framework for the rational design of affinity sorbents based on cellulose materials as a support. A three-level evaluation procedure, utilizing the knowledge of physical, chemical and engineering theories, is discussed, which integrates the design of support, affinity sorbent and chromatographic contactor. The principal support properties, such as morphological, diffusional, hydrodynamic, mechanical or ligand-binding properties, are presented and literature data on them are surveyed.
