The green approachable of metal nanoparticles is treated to be an eco-friendly path and cost-effectiveness. In this present study, nano copper was synthesized profitably by Cissus vitiginea. The synthesized nano copper was used to evaluate the antioxidant and antibacterial activity against urinary tract infections pathogens. The resulting constructed nanoparticles were characterized by using ultraviolet spectroscopy absorbance around 370 nm. Scanning electron microscopy results showed the distribution of nanoparticles and particles sizes are found to be in the range of 5-20 nm. X-ray diffraction spectrum characteristic diffraction peaks for copper nanoparticles were observed at 2θ ranges 35.5 and 43.2° correspond to lattice planes (1 1 1) and (2 0 2), respectively. X-ray photoelectron spectroscopy shows that two distinct peaks at binding energy resulted that the chemical states of copper. The results serve the evidence that the green mediated nano copper might indeed be the potential source to treat urinary tract infections caused by E. coli, Enterococcus sp., Proteus sp. and Klebsiella sp. This fact-finding conclusion is that C. vitiginea leaf extract based green synthesis nano copper particles proved to effectively kill it or significantly inhibit activity contra to urinary tract infection pathogens and exhibit excellent antioxidant activity.

使用Visstigus Vitiginea绿色合成铜纳米颗粒及其抗尿路感染病原体的抗氧化和抗菌活性。

金属纳米颗粒的绿色可接近性被视为一条生态友好的道路,并具有成本效益。在本研究中,Citsus vitiginea有利地合成了纳米铜。合成的纳米铜用于评估对尿路感染病原体的抗氧化和抗菌活性。通过使用370nm附近的紫外光谱吸收来表征所得的构造的纳米颗粒。扫描电子显微镜结果表明,发现纳米颗粒的分布和粒径在5-20nm范围内。在对应于晶格平面(1 1 1)和(2 0 2)的2θ范围35.5和43.2°处观察到铜纳米粒子的X射线衍射光谱特征衍射峰。X射线光电子能谱显示在结合能处的两个不同的峰导致了铜的化学态。该结果证明绿色介导的纳米铜确实可能是治疗由大肠杆菌,肠球菌,变形杆菌引起的尿路感染的潜在来源。和克雷伯菌属。这个事实发现的结论是,证明了基于虎斑假单胞菌叶提取物的绿色合成纳米铜颗粒可以有效地杀死它或显着抑制与尿路感染病原体相反的活性,并表现出优异的抗氧化活性。
