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

Magnetic Nanoparticles in Agriculture: Unraveling the Impact of Nickel Ferrite Nanoparticles on Peanut Growth and Seed Nutritional Quality

Plants, Journal Year: 2025, Volume and Issue: 14(7), P. 1011 - 1011

Published: March 24, 2025

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.

Nanomaterials in Broccoli Production: Current Applications and Future Prospects

Agronomy, Journal Year: 2025, Volume and Issue: 15(5), P. 1193 - 1193

Published: May 15, 2025

Conventional pesticides and fertilizers are frequently linked to high resource consumption, environmental damage, poor nutrient usage efficiency in the production of broccoli. Nanofertilizers (e.g., iron, copper, zinc oxide, boron NMs) pesticide nanoparticles (NPs) examples nanotechnology that is mainly related broccoli production. These technologies can increase uptake utilization as well broccoli’s resistance drought, heavy metal stress, saline alkaline other conditions. Through accurate fertilization dosing, reduce contamination need for traditional chemical fertilizers. Crops with nanomaterials have higher micronutrient content better nutritional quality. This study examines use broccoli, which could improve crop yield However, much research still required determine how affect environment whether or not they might be hazardous because their minuscule particle size unique physical characteristics. Researchers agricultural professionals both within outside field nanobiotechnology will able choose right help information presented this paper. The costs support sustainable growth. Additionally, it opens up new possibilities future production, transportation, storage cruciferous vegetables.
