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

Nanotechnology has been a source of innovation in various fields recent years, and its application agriculture attracted much attention, particularly for potential to enhance crop growth optimize nutritional quality. This study systematically investigated the effects nickel ferrite nanoparticles (NiFe2O4 NPs) on peanut (Arachis hypogaea L.) growth, nutrient dynamics, biochemical responses, highlighting their as sustainable alternatives conventional fertilizers. The results showed that an optimum concentration 50 mg/kg soil significantly improved photosynthetic efficiency, biomass accumulation, seed yield, quality, with 1000 weight total yield increasing by 12.3% 15.6%, respectively. In addition, we hypothesized NiFe2O4 NPs would activate antioxidant system increase plant resistance. According risk assessment, target hazard quotient (THQ = 0.081) is well below safety threshold 1. These findings provide strong evidence next-generation nano-fertilizers, offering dual advantage agronomic performance biosafety. However, further research needed strategies assess long-term environmental impacts.
