Abstract

quantification with a limit of detection (LOD) of 32 nM under optimized conditions. The modified electrode was further used to quantify dopamine, achieving an LOD of 0.81 µM, with a remarkably shorter detection time (60 fold shorter) compared to the conventional nanozyme. A mechanistic study showed that Co-MOF provides a large surface area and abundant redox-active sites, facilitating fast electron transfer and significantly enhancing the electrochemical signal.
