Carboxylated β-cyclodextrin anchored hollow mesoporous silica enhances insecticidal activity and reduces the toxicity of indoxacarb

Nanotechnology-Based Bioactive Antifeedant for Plant Protection

“…While nanospheres are designed as dense spherical vesicular systems in which active compounds are evenly distributed via adsorption or trapping in the nanomatrix/polymer, the cross-linked nanoparticles of the entrapped active compounds are mediated by ligands that act as sensors or markers for specific receptor molecules in targeted delivery. These efficient encapsulations and smart entrapped nano-carrier systems were confirmed to load the EO or pure active compounds with quite a high loading capacity with lethal and sublethal bioactivities due to a controlled slow-release mechanism [78,[84][85][86]88].…”

“…Recently, materials from natural polysaccharides, proteins, alginates, silica, and other types of polymers have been utilized as nanoparticle encapsulants, such as chitosan, zein, gum arabic, and silica nanoparticles [31,78,82]. Botanical active compounds have also been reported to be successfully loaded in a nanocapsule and being mesoporous for the slow-release system as well as being entrapped in the matrix polymer and the cross-linked nanoparticles mediated by specific ligands [83][84][85][86]. It is well known that the characteristic content of organic active compounds inherent in botanical ingredients is that they are easily degraded and, consequently, have a lower long-term potency [12].…”

Synthesis, antifungal evaluation, and safety assessment of mesoporous silica nanoparticles loaded with prothioconazole against crop pathogens

“…A Jupiter thermogravimetric analyzer (TGA) (STA 449 F5 Jupiter@, NETZSCH, Germany) was used to measure thermogravimetric losses of MSNs and Prot@MSNs. 40 Under N 2 protection, the temperature in the analyzer was increased from 30 to 800 °C at a rate of 10 °C min −1 . Then, the loading content of prothioconazole in Prot@MSNs was calculated.…”

A pH‐ and redox‐stimulated responsive hollow mesoporous silica for triggered delivery of fungicides to control downy mildew of Luffa cylindrica

“…As an effective method to solve these problems, the nanopesticide controlled‐release system has good application prospects because of improving pesticide efficiency and reducing environmental pollution 4 . A variety of nanoparticles have been used as pesticide carriers, and among these nanoparticles, hollow mesoporous silica (HMS) has received considerable attention due to its excellent biocompatibility, high loading efficiency, good controlled‐release ability, and easy surface modification 5 . To date, mesoporous silica formulations with different controlled‐release properties, such as light, pH, 6 temperature, 7 redox potential, enzymes, and different gating structures have been widely reported as pesticide carriers 8 .…”
