Iron-based metal-organic frameworks (Fe-MOFs) are widely used for agricultural chemical delivery due to their high loading capacity, and they also have the potential provide essential iron plant growth. Therefore, hold significant promise applications. Evaluating biotoxicity of Fe-MOFs is crucial optimizing use in agriculture. In this study, we natural biomacromolecule carboxymethyl cellulose (CMC) encapsulate Fe-MOF NH2-MIL-101 (Fe) (MIL). Through hydroponic experiments, investigated biotoxic effects on rice before after CMC modification. The results show that accumulation dependent dose exposure concentration Fe-MOFs. modification (MIL@CMC) can reduce release rate Fe ions from aqueous solutions with different pH values (5 7). Furthermore, MIL@CMC treatment significantly increases absorption by both aboveground root parts rice. alleviated growth inhibition seedlings increased biomass under medium- high-exposure conditions. Specifically, roots, MIL induced a more intense oxidative stress response, activities related antioxidant enzymes (CAT, POD, SOD) MDA content. Our demonstrated encapsulation NH2-MIL-101(Fe) using effectively damage promoted uptake These findings suggest rational positive effect reducing phytotoxicity MOFs improving biosafety
