Cyclodextrin polymer-valved MoS2-embedded mesoporous silica nanopesticides toward hierarchical targets via multidimensional stimuli of biological and natural environments

Supramolecular Biopharmaceutical Carriers Based on Host–Guest Interactions

“…For the application of cross-linked cyclodextrin carriers in pesticides, the authors encapsulated the fungicide tebuconazole (Teb) within mesoporous silica shell followed by MoS 2 @MSN surface functionalization and CDP encapsulation to form multivalent supramolecular nanovalves MoS 2 @MSN@CDP for controlled release of pesticides. 60 The results showed that the MoS 2 @MSN@CDP nanopesticides were well dispersed in water. When the nanopesticide diffuses on crop leaves, the hydrophobic component of the epidermal wax binds CDP as a competitive host, triggering the activation of the nanovalve to disengage and the release of the pesticide.…”

Recent advances in the design of controlled- and sustained-release micro/nanocarriers of pesticide

“…[29][30][31] The modified nanomaterials also provide other benefits including enhanced leaf adhesion and flush resistance to placate various pressing biotic and abiotic stresses (for example, heat, drought, salinity excess, light, drought and nutrient deficiency). 11,[32][33][34] Metal materials, mesoporous silicon nanoparticles (MSNs), 35,36 carbon nanotubes, 37 biochar 16 and synthetic polymers are commonly used to construct carriers due to their large specific surface area and high porosity. In addition, natural polymers (e.g., lignin, cellulose, lipid) with good renewability and biocompatibility have been used to construct controlled-and sustainedrelease micro/nanocarriers.…”

Facile Synthesis of the Dual Pesticide-Loaded Metal–Organic Framework Hybrid for pH-Responsive Release

“…One elegant strategy to solve the low utilization rate of pesticides would be to construct controlled release formulations. , The active ingredients are combined with carriers by physical or chemical methods, and their controllable release can be achieved through intelligent responses to the surrounding microenvironment. − At present, the carriers of pesticides usually include natural polymers, ,, inorganic materials, − covalent–organic frameworks, , and metal–organic frameworks (MOFs). − In particular, MOFs are widely used in the field of precision chemistry and are currently being integrated into the development of agriculture, making it more precise, efficient, and safe. MOFs are porous hybrid materials constructed by inorganic metal ions and organic ligands .…”
