Abstract

The use of plant extract to synthesize nanoparticles has transformed the area of nanotechnology. Silver nanoparticles (AgNPs) were generated in this work using the leaves of Cocculus pendulus as a reducing and stabilizing agent. The extract of C. pendulus was analyzed using a gas chromatography-mass spectrometer. UV-visible spectroscopy (UV-visible), Fourier Transform Infrared, Zeta potential, and Transmission Electron Microscopy were used to analyze the bio-fabricated AgNPs. In addition, we describe the antibacterial and antioxidant characteristics of AgNPs produced. Analyses were used to describe the morphology of produced AgNPs, which had a typical size of 45 nm. AgNP was discovered to be extremely poisonous to gram-positive bacteria and was a promising antibiotic against bacterial infections. Furthermore, antioxidant assays revealed the greatest free radical scavenging activity. Finally, our findings show that C. pendulus can be used as a source for green synthesis of AgNPs with strong antioxidant and antibacterial properties in vitro.

使用悬垂藻提取物绿色合成银纳米颗粒：形态学和对常见医院病原体的抗菌功效

摘要

使用植物提取物合成纳米颗粒已经改变了纳米技术领域。在这项工作中，使用悬垂藻的叶子作为还原剂和稳定剂生成了银纳米颗粒（AgNP）。使用气相色谱-质谱仪分析悬铃木提取物。紫外可见光谱（UV-visible）、傅里叶变换红外、Zeta 电位和透射电子显微镜用于分析生物制造的 AgNP。此外，我们还描述了所生产的 AgNP 的抗菌和抗氧化特性。分析用于描述所产生的 AgNP 的形态，其典型尺寸为 45 nm。 AgNP被发现对革兰氏阳性菌具有剧毒，是一种很有前途的对抗细菌感染的抗生素。此外，抗氧化剂测定显示出最大的自由基清除活性。最后，我们的研究结果表明，C. pendulus可作为体外绿色合成具有强抗氧化和抗菌特性的 AgNP 的来源。
