Water-soluble CS with different DS were synthesized by homogeneous conversion of cellulose (microcrystalline cellulose and spruce sulfite pulp) with different sulfating agents in the ionic liquids BMIMCl, AMIMCl and EMIMAc. N,N-Dimethylformamide was used as a dipolar aprotic co-solvent in order to improve the miscibility of the reaction mixture. The CS prepared by the new homogeneous reaction pathway were studied towards the formation of PEC capsules. CS obtained from SSP formed mechanically stable PEC capsules with Poly-DADMAC. Exploiting this method, the microencapsulation of glucose oxidase was studied and enzyme activity tests were performed with encapsulated GOD.
