Conventional agrochemicals are underutilized due to their large particle sizes, poor foliar retention rates, and difficult translocation in plants, the development of functional nanodelivery carriers with high adhesion plant body surface efficient uptake plants remains challenging. In this study, a system based on pectin-encapsulated iron-based MOF (TF@Fe-MOF-PT NPs) was constructed enhance utilization thifluzamide (TF) rice by taking advantage pectin affinity for cell walls. The prepared TF@Fe-MOF-PT NPs exhibited an average size 126.55 nm, loading capacity 27.41%, excellent dual-stimulus responses reactive oxygen species pectinase. Foliar washing experiments showed that were efficiently adhered surfaces leaves stems. Confocal laser scanning microscopy fluorescently labeled bidirectionally delivered through vascular bundles plants. vitro bactericidal activity better inhibitory than TF suspension (TF SC), EC50 0.021 mg/L. A greenhouse test more effective SC at 7 14 d, control effects 85.88 78.59%, respectively. It also reduced inhibition seed stem length root promoted seedling growth. These results demonstrated can be used as pesticide delivery intelligent release applied sustainable pests diseases.

Metal–organic framework nanoparticles (MOF NPs) have received much attention for their potential use in nanopesticides. However, little is known about the health and environmental risks associated with these materials. In this study, toxicological responses of zebrafish exposed to five MOF NPs short long periods time were evaluated. The acute toxicity results showed that embryos adult was order Cu-MOF > ZIF-90 ZIF-8 Fe-MOF Zr-MOF. Histopathological analysis revealed ZIF-8, ZIF-90, caused liver swelling vacuolization zebrafish. cellular ultrastructure severely damaged mitochondrial structure intestinal epithelial cells cells. 16S rDNA sequencing data all significantly altered dominant microorganisms intestine. microbial markers inflammation, Proteobacteria (Aeromonas, Plesiomonas, Legionella), increased Fe-MOF, Zr-MOF, treatment groups. Metabolomics indicated levels inflammatory promoting factors (Leukotriene E4, 20-hydroxyeicosatetraenoic acid) arachidonic acid metabolism decreased, suppressing (8,9-epoxyeicosatrienoic increased. Metabolites related oxidative stress, such as glutamine, pyridoxamine, l-glutamic vitamin B6 other signaling pathways, reduced. Overall, suggest different had widely varying zebrafish, further should be paid real environment.

Two Birds with One Stone: Eco‐Friendly Nano‐Formulation Endows a Commercial Fungicide with Excellent Insecticidal Activity

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Янв. 28, 2025

Abstract The development of multi‐action pesticides presents significant advantages, including cost‐effectiveness, reduced application frequency, enhanced resistance management, and minimized environmental impact. Despite its efficacy in targeting chitin synthase both fungi insects, the insecticidal performance polyoxin B remains limited. To overcome this limitation, a novel nano‐formulation, B@ZTS is developed, utilizing agricultural byproducts, tea saponin, zein. This formulation features small particle size, high leaf deposition efficiency, excellent dispersion properties. Leveraging disulfide bond system, designed to respond intracellular reducing environment, enabling controlled release B. Remarkably, nano‐formulation facilitates penetration physiological barriers, achieving equivalent fungicidal at only one‐fifth dosage. work highlights potential eco‐friendly, cost‐effective, multifunctional nano‐pesticides, providing compelling solution for sustainable practices demonstrating broad applicability integrated pest disease management.

Abstract Pathogenic bacterial infections pose a major concern, especially concerning mammalian enteritis and diarrhea. Compared to conventional antibiotic intervention, metal–organic frameworks (MOFs) exhibit superior antibacterial properties lower cytotoxicity, demonstrating great promise in the treatment of pathogen‐induced However, achievement their precise targeted delivery is still significant challenge. Herein, novel precision nano‐system with dual‐targeting approach for treating intestinal caused by Escherichia coli (E. coli) designed. First, Zn‐MOF was synthesized based on ZnO, which possessed enhanced elimination planktonic bacteria biofilms. Through mannosylation, Zn‐MOF@Man specifically recognized FimH pili E. , leading its aggregation subsequent eradication. Second, guided whole genome sequencing, encapsulation Lactobacillus biofilm exertd immunomodulatory function, overcomed challenges related targeting, facilitated sustained drug release. Furthermore, Zn‐MOF@Man/LRB maintaind microbiota equilibrium promoted stem cell differentiation barrier stability, ensuring consistent anti‐diarrheal anti‐inflammatory efficacy mice, piglets, humans.
