The green approach-based nanoparticle synthesis is considered a more cost-effective and ecologically responsible method of producing nanoparticles than other standard techniques. A major accomplishment in resolving these issues is the use of nanoparticles for environmental pollution remediation. This article describes a simple method for producing MgO and ZnO nanoparticles (NPs) using aqueous extracts of and roots as the stabilizing and reducing agents, respectively. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersed X-ray (EDX) spectroscopy methods were used to characterize the biologically synthesized metal oxide nanoparticles (MO NPs). The XRD results showed that the mean crystallite sizes of synthesized ZnO and MgO NPs, which have excellent purity, are 12.35 nm and 4.83 nm, respectively. The spherical or elliptical shape of the synthesized NPs was confirmed by the SEM analysis. The antibacterial activity of the synthesized NPs against both Gram-negative and Gram-positive bacteria was thoroughly investigated. With a medium zone of inhibition of 7 to 10 mm, the as-synthesized MgO NPs and ZnO NPs demonstrated moderate antibacterial activity towards various bacterial strains.
与其他标准技术相比，基于绿色方法的纳米颗粒合成被认为是一种更具成本效益且对生态负责的纳米颗粒生产方法。解决这些问题的一项重大成就是利用纳米颗粒进行环境污染修复。本文描述了一种分别使用[植物名称1]和[植物名称2]根的水提取物作为稳定剂和还原剂来制备氧化镁（MgO）和氧化锌（ZnO）纳米颗粒（NPs）的简单方法。采用傅里叶变换红外光谱（FTIR）、X射线衍射（XRD）、扫描电子显微镜（SEM）和能量色散X射线（EDX）光谱方法对生物合成的金属氧化物纳米颗粒（MO NPs）进行表征。XRD结果表明，合成的具有优异纯度的ZnO和MgO NPs的平均微晶尺寸分别为12.35 nm和4.83 nm。SEM分析证实了合成的NPs呈球形或椭圆形。对合成的NPs对革兰氏阴性菌和革兰氏阳性菌的抗菌活性进行了深入研究。合成的MgO NPs和ZnO NPs对各种细菌菌株表现出中等抗菌活性，抑菌圈直径在7至10 mm之间。
