Abstract ZnO QDs (zinc oxide quantum dots) have potential value in the field of silicone rubber due to their excellent antimicrobial properties. However, poor dispersion limits application. The surface functionalization can improve rubber. This study showed that could be effectively functionalized by using different kinds silane coupling agents KH550 (3‐aminopropyltriethoxysilane), KH570 (3‐acryloyloxypropyltrimethoxysilane), KH580 (3‐mercaptopropyltriethoxysilane), A151 (vinyltriethoxysilane) and HD128 (phenyltriethoxysilane). surface‐functionalized show a reduction particle size 4–5 nm. number agglomerated particles on QDs/RTV (room temperature vulcanized rubber) composites were significantly reduced. Meanwhile, roughness decreased 92.10% (KH550), 93.08% (KH570), 91.36% (KH580), 85.43% (A151), 90.86% (HD128), respectively, viscosity was increased 2.90% 4.35% 1.54% 3.62% respectively. QDs‐KH570 has best effect. Furthermore, antibacterial rate QDs‐KH570/RTV against Escherichia coli Staphylococcus aureus achieved 99.9% when additional amount ZnO‐KH570 0.1%, which indicated performance contribute development medical supplies.

In this study, the capacity of ubiquitous filamentous fungus Penicillium sp. 8L2 to remove Zn(II) ions present in synthetic solutions was studied and optimal operating conditions were obtained based on a response surface methodology (RSM). The contact time optimized through kinetic tests. Equilibrium tests then carried out, which allowed biosorption isotherms be for several mathematical models. At same time, fungal cell extract transform metal into ZnO nanoparticles with biocidal evaluated. Its inhibitory five microbial strains determined. mechanisms nanoparticle synthesis characterized by different crystallographic, spectrophotometric microscopic analytical techniques. It confirmed that bound superficially but also periplasmic space strong bond phosphate groups, both stage during consolidation nanoparticles. addition, presence hydroxyl, amino, carbonyl methylene groups identified, could promote nanoparticles, since some them have reducing nature. kinetics showed occurred two stages, first very fast second slower. identified maximum 52.14 mg/g Langmuir model under conditions: 5 days, pH 5.6 0.2 g/L biomass dose. success biological route an average size 18 nm obtained. data good inhibition ability against tested microorganisms, values ranging from 62.5 1000 µg/mL. is promising microorganism field heavy applied biotechnology.

Pathogenic bacteria pose significant threats to human health. In recent years, escalating bacterial resistance against antibiotics has diminished their efficacy in treating infections like pneumonia, tuberculosis, and sepsis, making some cases virtually untreatable. Hence, there is an urgent demand for novel approaches combat threats. Group IB metal‐based nanomaterials including copper, silver, gold have attracted considerable attention the field of antibacterial research owing remarkable broad‐spectrum bactericidal properties. Their high efficacy, ease synthesis, amenability functionalization render group highly promising diverse applications domain. This review comprehensively elucidates on mechanisms IB‐group addressing infections. Additionally, insights into challenges associated with utilizing such purposes while outlining future directions are provided.

This study evaluated the effects of ZnO and green-synthesized nanoparticles (ZnO-NPs) from Sargassum ilicifolium extract on biochemical interactions between tomato leaves destructive pest Tuta absoluta. The average size stability ZnO-NPs were characterized using DLS, X-RD, FE-SEM. Peaks in FT-IR spectrum algae ZnO-NPs, indicated presence carboxyl groups, amines, alkynes alcohols. Treated exhibited increased total chlorophyll anthocyanin contents, particularly at 100 50 ppm, compared to control. A significant increase flavonoid content was observed while phenolic also enhanced ppm. In T. absoluta larvae, exposure ppm led a reduction α-amylase, protease, protein, TAG levels, alongside catalase activity. Additionally, G6PD ALT activities decreased Lactate, MDA, RSSR/RSH Furthermore, elevated larval aldolase activity, AST γ-GT declined. These findings indicate that enhance defense mechanisms mitigate damage, supporting their potential use integrated management strategies against
