Abstract
Enzymes immobilized in carrier materials are useful to control chemical reactions. Phospholipid vesicles (liposomes) possess compartmentalized aqueous phase and lipid bilayer membranes in which different enzyme molecules can be confined for various biotechnological applications. In this review, characteristic features of the preparation methods of liposomes being encapsulated or chemically conjugated with the enzyme molecules are described. Then, applications of the liposomal systems are described with respect to the stabilization of thermally denatured enzymes and a catalytic cascade reaction. Current progress and perspective of relevant researches are briefly mentioned.
