Polyelectrolyte Synthesis and in Situ Complex Formation in lonic Liquids

摘要

State of the art biotechnological processes use immobilization of biological materials, in particular enzymes, to guarantee durability, to simplify workup steps, and to allow enzyme recovery. Polyelectrolyte complex (PEC) capsules constructed from biocom-patible polyelectrolytes are well suited for the entrapment of bioactive species. One potential candidate is the polyanion cellulose sulfate (CS). Although the usefulness of enzyme entrapment in CS-based PEC is well recognized, the multistep process is time-consuming and inefficient preventing broad application.
