Self-assembled nanozyme complexes with enhanced cascade activity and high stability for colorimetric detection of glucose

In this work, a hybrid multi-enzyme system, CeO2/glucose oxidase (GOx) nanocomplex was developed via self-assembly and exhibited excellent catalytic activity toward cascade reactions, offering a simple and efficient example to build spatially confined multi-enzyme systems to potentiate their applications in energy conversion, detoxification and bioanalysis.
