There is a growing interest in the utilization of metal oxide nanoparticles as antimicrobial agents. This review will focus on titanium dioxide (TiO2 NPs), which have been demonstrated to exhibit high activity against bacteria and fungi, chemical stability, low toxicity eukaryotic cells, therefore biocompatibility. Despite extensive research conducted this field, there currently no consensus how enhance efficacy TiO2 NPs. The aim evaluate influence various factors, including particle size, shape, composition, synthesis parameters, well microbial type, antibacterial NPs fungi. Furthermore, offers comprehensive overview methodologies employed characterization exhibits weak dependence microorganism species. A tendency towards increased observed with decreasing NP size. shape composition more pronounced. most pronounced potential exhibited by amorphous doped inorganic compounds. may be specialists biology, medicine, chemistry, other related fields.

Mg(OH)2 was used as the nanocarrier of Bacillus thuringiensis (Bt) Cry1Ac protein, and synthesized Cry1Ac–Mg(OH)2 composites were regular uniform nanosheets. Nano-Mg(OH)2 could effectively improve insecticidal effect protein toward Ectropis obliqua. It enhance damage degree to intestinal epithelial cells microvilli, induce enrich production reactive oxygen species (ROS) in midgut, degradation into active fragments. Furthermore, an anti-rinsing assay showed that bound notch structure tea leaf surface. The retention increased by 11.45%, sprayed nano-Mg(OH)2 rapidly absorbed different tissues plants. Moreover, did not significantly affect non-target organisms. These results show can serve a safe effective biopesticide carrier, which provides new approach for stable efficient Bt preparation.

Soil salinization is one of the global ecological and environmental problems that are tremendously threatening to sustainable development agriculture food supply. In this work, a facile strategy was proposed enhance salt stress resistance plants by preparing salicylic acid (SA)-functionalized mesoporous silica nanocarriers loaded with emamectin benzoate (EB). The obtained nanopesticides demonstrated particle size less than 300 nm. As an endogenous plant hormone, grafting SA in nanopesticide system improved uptake translocation pesticides cucumber 145.06%, applications such enhanced plants. This phenomenon accounted for SA-functionalized increasing superoxide dismutase peroxidase activities (640 175%, respectively) reducing malondialdehyde content (54.10%), correspondingly alleviating accumulation reactive oxygen species cell damage above results were also confirmed Evans blue staining NBT experiments on leaves. addition, these exhibited high insecticidal toxicity, they biosafety toward nontarget organisms due their sustained release property. Therefore, work developed biosafe system, newly have potential agricultural field enhancing

Nano-TiO2 as an antimicrobial inorganic material, can stimulate cells to produce reactive oxygen species and exhibit effective biochemical properties; however, phenylpyrazole derivatives, organic pesticides, are widely used in agriculture food. To find novel pesticides with environmental friendliness, combined three-dimensional quantitative structure-activity relationship (3D-QSAR) prediction analysis, three types of alkaloidal amine derivatives (PA) were synthesized by a one-pot microwave method. Based on the dye sensitization strategy, four nano-organometallic (PT) prepared organic-inorganic hybridization. PA PT showed 2.5 5.2 times higher insecticidal activity against P. xylostella than fipronil, had 3.9 greater antibacterial A. tumefaciens. The synergistic effect realizes balance amphiphilicity, enhances biological PT, improves phloem fluidity, promotes absorption transportation substances. In addition, this reduces band gap width, light capacity, induces active free radicals (ROS: ·O2-, ·OH), destroys cytomembrane so that better enter cell, resulting cell death. has excellent natural self-degradation performance converts parent moiety, which greatly residues, implying pesticide provides new idea for its degradation fluorescence detection residues.
