Although various MOFzymes have been used for H2O2 detection, their application in leafy vegetables remains limited. This was primarily due to the interference of complex matrices vegetables, which affected detection process. Additionally, free catalytic metal could lead color fading, resulting unstable and time-consuming reactions. In this study, inspired by multiactive sites high selectivity iron porphyrin-based MOFzymes, along with enhanced stability chelated iron, we developed a highly sensitive selective PCN222(Fe)-Gly(Fe)2. enzyme zirconium as center, porphyrin organic ligand, ferrous glycine modifier. While advantages were retained, synergistic impact internal Fenton-like reaction improved rate, leading remarkable 310.2% increase velocity. field testing environments, content Pakchoi seedling leaves be determined within 100 s. addition, sensor demonstrated practical utility predicting shelf life freshness seedlings.
