Enzymes are known for their remarkable catalytic efficiency across a wide range of applications. Here, we present novel and convenient nanoreactor platform based on zwitterionic polyelectrolyte complex vesicles (PCVs), assembled from oppositely charged homopoly(2-oxazoline)s, facilitating enzyme immobilization. We show enhancements in activity stability by encapsulation lipase as model enzyme. Even the temperature rises, performance remains robust. Further, structural characteristics PCVs, including hollow architecture semipermeable membranes, endow them with unique advantages cascade reactions involving glucose oxidase (GOx) horseradish peroxidase (HRP). A decline is shown when enzymes individually loaded subsequently mixed, contrast to coloaded GOx–HRP–PCV group. demonstrate that vesicle structures establish confined environments where precise enzyme–substrate interactions facilitate enhanced efficiency. In addition, nanoreactors exhibit excellent biocompatibility efficient anti-tumor activity, which hold significant promise biomedical applications within enzyme-based technologies.
