The present work deals with the ultrasound assisted green synthesis of iron oxide nano particle using Coriandrum sativum leaf extract as a reducing agent. The synthesized iron oxide nanoparticle was confirmed by UV spectra. The characterization was done to know more about morphology and size of the particle by SEM analysis which shows spherical particles with size ranging from 20 to 90nm. The antimicrobial activity of the leaf extract and the synthesized nanoparticles was studied against the pathogens Micrococcus luteus, Staphylococcus aureus and Aspergillus niger. The ultrasound assisted iron oxide nanoparticle shows higher scavenging activity and antimicrobial activity compared with iron oxide nanoparticle synthesized by magnetic stirrer and Coriandrum sativum leaf extract.
本工作采用芫荽叶提取物作为还原剂，通过超声辅助法绿色合成了氧化铁纳米粒子。通过紫外光谱证实了合成的氧化铁纳米粒子的存在。通过 SEM 分析对粒子的形貌和尺寸进行了进一步的表征，结果表明粒子呈球形，尺寸范围为 20-90nm。研究了芫荽叶提取物和合成的纳米粒子对病原体微球菌、金黄色葡萄球菌和黑曲霉的抗菌活性。与通过磁力搅拌和芫荽叶提取物合成的氧化铁纳米粒子相比，超声辅助氧化铁纳米粒子具有更高的清除活性和抗菌活性。
