PEG-directed structural modulation of short hexagonal Co-nanozyme: enhanced aqueous stability, high peroxidase activity and colorimetric detection of H2O2 and dopamine.
Nanozyme offers promising alternatives to natural enzymes, but has poor aqueous stability and aggregation, which limit their practical applications. In this work, a polyethylene glycol (PEG)-modulated short hexagonal-Co-nanozyme was synthesized via co-precipitation methods to address these limitations. Different PEG mo...
