Present work compares the green synthesis of iron oxide nanorodes (NRs) using Withania coagulans and reduction precipitation based chemical method. UV/Vis confirmed the sharp peak of Iron oxide NRs synthesized by biologically and chemically on 294 and 278 nm respectively. XRD and SEM showed highly crystalline nature of NRs with average size 16 ± 2 nm using Withania extract and less crystalline with amorphous Nanostructure of 18 ± 2 nm by chemical method. FTIR analysis revealed the involvement of active bioreducing and stabilizing biomolecules in Withania coagulans extract for synthesis of NRs. Moreover, EDX analysis indicates 34.91% of Iron oxide formation in biological synthesis whereas 25.8% of iron oxide synthesis in chemical method. The degradation of safranin dye in the presence of Withania coagulans based NRs showed 30% more effectively than chemically synthesized Nanorods which were verified by the gradual decrease in the peak intensity at 553 nm and 550 nm respectively under solar irradiation. Furthermore, Withania coagulans based NRs showed effective Antibacterial activity against S.aureus and P. aeuroginosa as compared to NRs by chemical method. Finally, we conclude that green synthesized NRs are more effective and functionally more efficient than chemically prepared NRs. Therefore, our work will help the researchers to boost the synthesis of nanoparticles via biological at commercial level.

使用Withania凝聚物的绿色合成氧化铁纳米棒改善了光催化降解和抗菌活性。

当前的工作比较了使用Withania凝聚剂和基于还原沉淀的化学方法绿色合成氧化铁纳米棒(NRs)的方法。UV / Vis证实了通过生物学和化学方法分别在294和278 nm上合成的氧化铁NRs的尖峰。X射线衍射和扫描电镜显示了使用Withania提取物的NR的高度结晶特性,平均尺寸为16±2 nm,而化学方法则显示出较少的结晶,具有18±2 nm的非晶纳米结构。FTIR分析表明,Withania凝聚物提取物中有活性的生物还原和稳定生物分子参与了NRs的合成。此外,EDX分析表明,在生物合成中形成了34.91%的氧化铁,而在化学方法中合成了25.8%的氧化铁。在基于Withania凝聚素的NRs中,番红花染料的降解显示出比化学合成的纳米棒高30%的效果,这可以通过分别在太阳辐射下在553 nm和550 nm处的峰值强度逐渐降低来证明。此外,与用化学方法的NRs相比,以Withania血凝素为基础的NRs显示出对金黄色葡萄球菌和金黄色葡萄球菌的有效抗菌活性。最后,我们得出结论,绿色合成的NRs比化学制备的NRs更有效,功能更有效。因此,我们的工作将有助于研究人员在商业水平上通过生物促进纳米颗粒的合成。与化学方法的NRs相比,以Withania凝聚素为基础的NRs对金黄色葡萄球菌和金黄色假单胞菌具有有效的抗菌活性。最后,我们得出结论,绿色合成的NRs比化学制备的NRs更有效,功能更有效。因此,我们的工作将有助于研究人员在商业水平上通过生物促进纳米颗粒的合成。与化学方法的NRs相比,以Withania凝聚素为基础的NRs对金黄色葡萄球菌和金黄色假单胞菌具有有效的抗菌活性。最后,我们得出结论,绿色合成的NRs比化学制备的NRs更有效,功能更有效。因此,我们的工作将有助于研究人员在商业水平上通过生物促进纳米颗粒的合成。
