Plohl, Olivija published the artcileMesoporous silica nanoparticles modified with N-rich polymer as a potentially environmentally-friendly delivery system for pesticides, Quality Control of 42822-86-6, the main research area is mesoporous silica nanoparticle nitrogen polymer pesticide.
The focus of the article is on the design of environmentally-friendly nanocarriers for improved controlled pesticide release, which have low environmental toxicity and nitrogen elemental composition as the most important components of fertilizers. In this study, a novel delivery system was developed for post-loading a biopesticide to mesoporous silica nanoparticles (MeSiNPs) functionalized with N-rich derived polymer. Initially, MeSiNPs were synthesized by the template-assisted method, which yielded MeSiNPs in the nm range, together with highly ordered mesoporous channels with a pore size of 2.9 nm. Subsequently, the water-soluble branched polyethyleneimine (bPEI) was derived systematically with epoxy organosilicate, and functionalized on MeSiNPs to create a source of N-nutrients. The carefully designed novel nano-carrier was analyzed by several physicochem. and structural analyses, which confirmed the successful attachment of the derived bPEI to MeSiNPs. Further, the novel nano-synthesized system was used as a delivery for the model biopesticide citridiol. The loading efficiency of citridiol in/on MeSiNPs@bPEI was 19%, while the loading capacity of citridiol was proven to be 5 mg biopesticide/1 mg MeSiNPs@bPEI. The MeSiNPs@bPEI with loaded citridiol was investigated for kinetic release. The system showed a fast initial release behavior in the first 300 min, which was continued by slow release behavior and started to reach equilibrium after 10 days. It has been shown that the MeSiNPs@bPEI showed an excellent potential for use in agrochem. applications, not only as a nanocarrier for controlled and slow pesticide release, but may also act as a soil improver by providing Si and N as key nutrient sources.
