Construction of a photothermal controlled-release microcapsule pesticide delivery system

Abstract

A photothermal controlled-release microcapsule pesticide delivery system was constructed using chitosan and polydopamine as the wall materials to encapsulate avermectin, the utilization rate of avermectin was improved.

Recent Development of Versatile Polyphenol Platforms in Fertilizers and Pesticides

“…A photothermal-controlled release microcapsule pesticide delivery system was constructed using chitosan and PDA to encapsulate avermectin, indicating its excellent slow release, UV shielding, and improved utilization of pesticides. 50 A pesticide bead was designed and prepared through the cooperative combination of kaolin, PDA, imidacloprid, sodium alginate, PNIPAm, detonation nanodiamonds, and amino silicone oil (Figure 6). 51 This stimuliresponsively controlled-release pesticide can regulate the drug release rate through pH-caused expansion and light-induced volume phase transition to adapt to the diurnal feeding habits of pests along with daylight changes.…”

Photothermal controlled‐release microcapsule pesticide delivery systems constructed with sodium lignosulfonate and transition metal ions: construction, efficacy and on‐demand pesticide delivery

“…13 Recently, a few photothermally controlled-release microcapsule pesticide-delivery systems have been reported. 14 Under irradiation with NIR light or light-emitting diode (LED)-simulated sunlight, these systems could effectively convert the harvested light into heat energy via non-emissive deactivation, thus increasing the temperature of the pesticide systems and triggering the release of pesticide active ingredients.…”

“…Currently, controlled‐release microcapsule pesticides have received extensive attention because the release of pesticide active ingredients can be effectively regulated by external stimuli‐responsive conditions such as pH, 7 temperature, 8 magnetism, 9 microbe, 10 near‐infrared (NIR), 11 ultraviolet (UV) light 12 and enzymes 13 .

Efficient Construction of pH-Stimuli-Responsive Colloidosomes with High Encapsulation Efficiency

“…Colloidosomes are microcapsules, whose shells are composed of cumulated or fused polymers. − In recent years, colloidosomes have attracted wide attention due to their structural diversity, for which they have been involved in various fields such as medicine, , agriculture, , energy, , and catalysis . Intelligent responsive colloidosomes can provide function-oriented structural designs that respond to small changes in environment, such as temperature, pH, − light, and ionic strength, , and their core substances are released to play a role in a specific situation.…”
