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 as a reducing and stabilizing agent. The extract of 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 can be used as a source for green synthesis of AgNPs with strong antioxidant and antibacterial properties .

摘要

利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[植物名称]的叶子作为还原剂和稳定剂来生成银纳米颗粒(AgNPs)。使用气相色谱 - 质谱仪对[植物名称]的提取物进行了分析。利用紫外可见光谱(UV - 可见)、傅里叶变换红外光谱、zeta电位和透射电子显微镜对生物合成的AgNPs进行了分析。此外,我们描述了所制备的AgNPs的抗菌和抗氧化特性。通过分析来描述所制备的AgNPs的形态,其典型尺寸为45纳米。发现AgNP对革兰氏阳性菌具有极高的毒性,并且是一种有前景的抗细菌感染抗生素。此外,抗氧化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,[植物名称]可用作绿色合成具有强抗氧化和抗菌性能的AgNPs的原料。
