Synthesis of highly dispersed zinc oxide nanoparticles on carboxylic graphene for development a sensitive acetylcholinesterase biosensor

- Highly dispersed ZnO NPs were synthesized of on carboxylic graphene surface.
- ZnO NPs-CGR showed excellent conductivity, catalytic activity and biocompatibility.
- We proposed a universal and effective method for immobilizing enzyme.
- A novel AChE biosensor based on ZnO NPs-CGR-NF has been developed.
