The use of eco-friendly methods for the synthesis of nanoparticles and its nano-composite has become a public demand nowadays to reduce the risks of chemical methods. In the current study, green synthesis of Cu-doped ZnO based polymers nan-ocomposite was performed. Various instrumental analysis including UV–vis, ATR-FTIR spectroscopy, XRD, SEM coupled with energy dispersive X-ray analysis, TEM and Thermal gravimetric were used to characterize nano-composite. Highly antibacterial activity of the synthesized nano-composite was recorded against tested microorganisms with promising efficacy against bacteria namely; Bacillus subtilis, Staphylococcus aureus, Enterococcus faecalis, Proteus vulgaris, Pseudomonas aeruginosa, Escherichia coli, Salmonella typhimurium and yeast (Candida albicans) but unfortunately not against black fungus (Mucor circinelloides) and filamentous fungi Aspergillus flavus and A. niger. Anti-inflammatory of nano-composite represented by hemolysis inhibition was observed at using low concentration (100 µg/mL) with enhancing 23.85% compared with free nano-composite while at high concentrations 500 and1000 µg/mL the anti-inflammatory activity was approximately similar with enhancing 3.91% and 1.99%, respectively. Antioxidant of the nano-composite was better than the antioxidant of free nano-composite at all tested concentrations, moreover the IC50 of the nano-composite (91.16 µg/mL) was less than the IC50, (203.65 µg/mL) of the free nano-composite.

原位绿色合成 Cu 掺杂 ZnO 基聚合物纳米复合材料,研究抗菌、抗氧化和抗炎活性

使用环保方法合成纳米粒子及其纳米复合材料已成为当今降低化学方法风险的公众需求。在目前的研究中,进行了Cu掺杂的ZnO基聚合物纳米复合材料的绿色合成。各种仪器分析,包括紫外-可见光、ATR-FTIR 光谱、XRD、SEM 结合能量色散 X 射线分析、TEM 和热重分析,用于表征纳米复合材料。合成的纳米复合材料对测试的微生物具有高度的抗菌活性,对细菌具有良好的功效;枯草芽孢杆菌、金黄色葡萄球菌、粪肠球菌、普通变形杆菌、绿脓杆菌、大肠杆菌、鼠伤寒沙门氏菌和酵母菌(Candida albicans),但不幸的是不能对抗黑木耳(Mucor circinelloides)和丝状真菌Aspergillus flavus 和A. niger。以溶血抑制为代表的纳米复合材料的抗炎作用在使用低浓度(100 µg/mL)时观察到,与游离纳米复合材料相比增强了 23.85%,而在高浓度 500 和 1000 µg/mL 时,抗炎活性大致相似分别提高了 3.91% 和 1.99%。在所有测试浓度下,纳米复合材料的抗氧化剂均优于游离纳米复合材料的抗氧化剂,而且纳米复合材料的IC50(91.16 µg/mL)低于游离纳米复合材料的IC50(203.65 µg/mL)。纳米复合材料。以溶血抑制为代表的纳米复合材料的抗炎作用在使用低浓度(100 µg/mL)时观察到,与游离纳米复合材料相比增强了 23.85%,而在高浓度 500 和 1000 µg/mL 时,抗炎活性大致相似分别提高了 3.91% 和 1.99%。在所有测试浓度下,纳米复合材料的抗氧化剂均优于游离纳米复合材料的抗氧化剂,而且纳米复合材料的IC50(91.16 µg/mL)低于游离纳米复合材料的IC50(203.65 µg/mL)。纳米复合材料。以溶血抑制为代表的纳米复合材料的抗炎作用在使用低浓度(100 µg/mL)时观察到,与游离纳米复合材料相比增强了 23.85%,而在高浓度 500 和 1000 µg/mL 时,抗炎活性大致相似分别提高了 3.91% 和 1.99%。在所有测试浓度下,纳米复合材料的抗氧化剂均优于游离纳米复合材料的抗氧化剂,而且纳米复合材料的IC50(91.16 µg/mL)低于游离纳米复合材料的IC50(203.65 µg/mL)。纳米复合材料。
