Microplasma-assisted synthesis of a mixed-valence Ce-MOF with enhanced oxidase-like activity for colorimetric sensing of dopamine

in a MVCM, the MVCM-based colorimetric sensing of dopamine was established and showed a limit of detection of 0.74 μM over a linear range of 5-100 μM with high selectivity and stability and has been applied for the detection of dopamine in sweat. The proposed study provides an effective synthesis method for nanozymes with enhanced activity and shows great promise in widespread analytical and sensing applications.
