Abstract

Enzyme immobilization is an essential prerequisite for biocatalysis. In this context, emulsion provides an excellent template for assembling Enzymes at the oil-water interface. A microfluidic approach has been adopted to produce oil-in-water-type emulsions stabilized by gold nanoparticle-catalase conjugates. In situ ring-opening polymerization of the oil phase produces solid core enzyme-immobilized microcapsules (MCs). These resultant MCs exhibited a K m value of 42 mM and shows 1.1-fold higher activity compared to free Enzymes. Finally, the robust MCs showed excellent recyclability, which can meet the demand of industrial biotechnological applications.
