Iron oxide nanoparticles (Fe₂O₃NPs) are an interested and attractive area of research as they have numerous effective environmental and biomedical applications. Herein we have reported a simple and eco-benign synthesis Fe₂O₃NPs using Tamarix aphylla extract. The extract of the Tamarix aphylla acts both as a reducing and capping agent which leads to the fast and successful eco-benign synthesis of Fe₂O₃NPs.UV/Vis spectroscopy, XRD, EDX, SEM and TEM techniques were used to characterize and explore different features ofFe₂O₃NPs. UV/Vis studies showed asharppeak at 390 nm due to surface plasmon resonance absorption of Fe₂O₃NPs. XRD studies indicated that Fe₂O₃NPs were crystalline in nature. Structural features, elemental composition and geometry ofFe₂O₃NPswere confirmed by SEM, EDX and TEM. The as synthesized Fe₂O₃NPs showed efficient efficacy to degrade 100% of Methylene blue (MB) dye by 4 mg/25 ml MB and revealed 90% scavenging of the more stable DPPH free radical(1 mg/ml). Furthermore, Fe₂O₃NPs showed excellent antimicrobial activity against pathogenic multidrug resistant bacterial strains. The results of the present study explored the potential reducing, capping property of Tamarix aphylla extract, photocatalytic and biomedical applications of eco-benignly synthesized Fe₂O₃NPs which could be an alternative material for effective remediation of lethal organic pollutants and microbes.

氧化铁纳米粒子（Fe ₂ O ₃ NPs）是一个有趣且有吸引力的研究领域，因为它们具有许多有效的环境和生物医学应用。在本文中，我们报道了使用柳叶柳提取物可简单且生态友好地合成Fe ₂ O ₃ NP 。Tamarix aphylla的提取物既用作还原剂，又用作封端剂，可快速成功地合成Fe ₂ O ₃ NPs的生态良性。紫外/可见光谱，XRD，EDX，SEM和TEM技术表征和探索Fe ₂ O _3的不同特征NP。UV / Vis研究表明，由于Fe ₂ O ₃ NPs的表面等离振子共振吸收，在390 nm处出现尖峰。XRD研究表明，Fe ₂ O ₃ NPs本质上是晶体。SEM，EDX和TEM证实了Fe ₂ O ₃ NPs的结构特征，元素组成和几何形状。所合成的Fe ₂ O ₃ NP显示出将4％/ 25 ml MB降解100％的亚甲基蓝（MB）染料的有效功效，并揭示了90％的更稳定的DPPH自由基（1 mg / ml）的清除能力。此外，Fe ₂ O ₃NPs对致病性多药耐药细菌菌株显示出优异的抗菌活性。本研究的结果探讨了塔玛柳提取物的潜在还原，加帽性能，生态良性合成的Fe ₂ O ₃ NPs的光催化和生物医学应用，这些材料可作为有效修复致命性有机污染物和微生物的替代材料。
