Abstract

The fabrication of the inorganic metal oxide nanoparticles by using extract of the different part of the plant was gaining an overwhelming response from the last few years. Magnetic iron oxide nanoparticles exhibiting verity of biomedical applications hence in the current proposed work we use an unexplored Euphorbia herita leaf extract in the green synthesis of magnetic iron oxide nanoparticles (Fe₃O₄ NPs). The tailored Fe₃O₄ NPs was structurally characterized by using advanced analytical tools like UV–visible spectroscopy, Scanning electron microscopy (SEM) analysis, Fourier transform infra-red (FT-IR) analysis and X-ray diffraction study. The fabricated nanoparticles were naturally stabilized, having cavity like structure with average particle size in the range of 25–80 nm. The phytochemicals especially polyphenols and alcoholic compound play crucial role in the fabrication of magnetic iron oxide nanoparticles. The antimicrobial activity of the fabricated iron oxide nano particles was evaluated against selected bacterial and fungal pathogen and the result of antimicrobial study was very promising.

摘要

使用植物不同部位的提取物制造无机金属氧化物纳米颗粒在过去几年中获得了压倒性的反响。磁性氧化铁纳米粒子表现出生物医学应用的真实性，因此在目前提出的工作中，我们在磁性氧化铁纳米粒子 (Fe ₃ O ₄ NPs)的绿色合成中使用了未开发的大戟叶提取物。量身定制的 Fe ₃ O ₄通过使用先进的分析工具，如紫外-可见光谱、扫描电子显微镜 (SEM) 分析、傅里叶变换红外 (FT-IR) 分析和 X 射线衍射研究，对纳米颗粒进行结构表征。制造的纳米粒子自然稳定，具有空腔状结构，平均粒径在 25-80 nm 范围内。植物化学物质，特别是多酚和醇类化合物在磁性氧化铁纳米粒子的制造中起着至关重要的作用。对制备的氧化铁纳米颗粒对选定的细菌和真菌病原体的抗菌活性进行了评估，抗菌研究的结果非常有希望。
