Preparation of a novel sustained-release system for pyrethroids by using metal-organic frameworks (MOFs) nanoparticle

Enhanced Fungicidal Efficacy by Co-Delivery of Azoxystrobin and Diniconazole with Cauliflower-Like Metal–Organic Frameworks NH2-Al-MIL-101

“…As an emerging class of porous materials, metal–organic frameworks (MOFs) with unique properties have been applied in many fields. At present, studies have been conducted on the use of MOFs in pesticides such as pesticide sensing [ 23 ], delivery [ 24 , 25 , 26 ], adsorption, and photodegradation [ 27 ]. In our previous work, we also prepared pesticide-loaded Fe-MIL-100 [ 28 ] and NH 2 -Fe-MIL-101 [ 29 ] and studied the controlled release profiles of AZOX and Dini, respectively.…”

Recent development in functional nanomaterials for sustainable and smart agricultural chemical technologies

“…MOFs could afford broad ranges of physical and chemical properties in addition to extremely high specific surface areas, and key components can be selected from a wide range of eco-friendly materials. In fact, it is believed that most MOFs can be ultimately decomposed to components to be absorbed by soil as nutrients [ 59 ]. Physical adsorption of active ingredients to pre-made MOFs is the most common strategy for nanopesticides fabrication using MOFs.…”

“…Physical adsorption of active ingredients to pre-made MOFs is the most common strategy for nanopesticides fabrication using MOFs. Studies have demonstrated that zirconium-, aluminum-, and iron-based MOFs synthesized via hydrothermal or microwave heating methods could achieved controlled release of various pesticides [ 59 – 61 ]. Additional regulation on release rate can be achieved by introducing additional components.…”

“…Biodegradable synthetic polymers, specially polylactic acid (PLA) and poly(lactic-co-glycolic acid) (PLGA) are also attractive candidates for nano entrapment. They can Porous Silica Nanosphere /Imidacloprid [49] Zirconium-based MOF /Pyrethroids [59] Iron-Based MOFs /Chlorantraniliprole [60] Aluminum-Based MOFs/ Azoxystrobin and Diniconazole [61] Iron-based MOFs /Diniconazole [62] Fe 3 O 4 -MOF Core-shell Nanocarrier/Imidacloprid [63] Zinc MOF /ortho-Disulfides Entrapment With Further Modification with β-Cyclodextrin [64] be eventually degraded into environment-friendly lactic acid and glycolic acid monomers, while their hydrophobic nature also offers a good affinity to pesticide molecules [38,39]. Employing PLA as the entrapping matrix, Liu and co-workers [40] prepared porous microspheres via a PME process to achieve sustained release of pesticide chlorantraniliprole.…”

Fe3O4 Magnetic Cores Coated with Metal–Organic Framework Shells as Collectable Composite Nanoparticle Vehicles for Sustained Release of the Pesticide Imidacloprid

“…An insect-dip method was used to investigate the toxicity of IMI@ Fe 3 O 4 @PDA@UiO-66 against Aphis craccivora Koch. 29 Free IMI, the commercial 70% IMI water dispersible granule (WG), Fe 3 O 4 @PDA@ UiO-66, and 0.05% Tween-80 aqueous solution were chosen as blank controls. IMI was dissolved in DMF (2 mL).…”
