plant extract mediated propellant chemistry route was used for the green synthesis of zinc oxide nanoparticles. Prepared samples were confirmed for their nano regime using advanced characterization techniques such as powder X-ray diffraction and microscopic techniques such as scanning electron microscopy and transmission electron microscopy. The energy band gap of the green synthesized zinc oxide (ZnO)-nanoparticles (NPs) were found between 3.25-3.28 eV. Fourier transmission infrared spectroscopy shows the presence of Zn-O bond within the wave number of 500 cm. SEM images show the specific agglomeration of particles which was also confirmed by TEM studies. The green synthesized ZnO-NPs inhibited the growth of and with a minimum inhibitory concentration (MIC) of 125 µg mL and 62.5 µg mL, respectively. The results indicate the prepared ZnO-NPs can be used as a potential antimicrobial agent against harmful pathogens.

采用植物提取物介导的推进剂化学途径，绿色合成了氧化锌纳米粒子。使用先进的表征技术，如粉末 X 射线衍射和显微镜技术，如扫描电子显微镜和透射电子显微镜，对制备的样品进行了纳米级别的确认。绿色合成的氧化锌 (ZnO)-纳米粒子 (NPs) 的能隙在 3.25-3.28 eV 之间。傅里叶传输红外光谱显示在 500 cm 的波数范围内存在 Zn-O 键。SEM 图像显示了颗粒的特定团聚，这也通过 TEM 研究得到了证实。绿色合成的 ZnO-NPs 对和的生长具有抑制作用，最低抑菌浓度 (MIC) 分别为 125 µg mL 和 62.5 µg mL。结果表明，所制备的 ZnO-NPs 可用作对抗有害病原体的潜在抗菌剂。
