The development of green nanotechnology is generating research interest in the ecological biosynthesis of nanoparticles (NPs). In this study, the biosynthesis of stable iron nanoparticles was carried out using Phoenix dactylifera L. extract which is able to reduce iron ions to iron nanoparticles. The process comprises maceration extraction overnight and heat treatment of the extract with iron chloride (FeCl3) at 70 °C for 1 h. X-ray diffraction (XRD), scanning electron microscope (SEM), and Fourier transform infrared spectroscopy (FTIR) were used for nanoparticle characterization. The stability of the bioreduced iron nanoparticle was analyzed using UV-VIS absorption spectra, and their antioxidant and anti-radical activities were measured against PhosPhoMolybdate (PPM) and 2,2-diphenyl-1-picryl-hydrazyl (DPPH), respectively. The results demonstrate that ecological biosynthesis of 2–30 nm stable iron nanoparticles of size with antioxidant activity can be achieved suggesting their possible applications.

菲尼克斯小叶菊叶提取物的绿色合成,氧化铁纳米粒子的表征及其抗氧化活性的评价

绿色纳米技术的发展引起了人们对纳米颗粒(NPs)的生态生物合成的研究兴趣。在这项研究中,使用Phoenix dactylifera L进行了稳定的铁纳米颗粒的生物合成。能够将铁离子还原为铁纳米颗粒的提取物。该方法包括将浸软浸提一整夜并用氯化铁(FeCl 3)在70°C下放置1小时。X射线衍射(XRD),扫描电子显微镜(SEM)和傅里叶变换红外光谱(FTIR)用于表征纳米粒子。使用UV-VIS吸收光谱分析了生物还原的铁纳米颗粒的稳定性,并分别测量了其对磷酰钼(PPM)和2,2-二苯基-1-吡啶基-肼基(DPPH)的抗氧化和抗自由基活性。结果表明,可以实现具有抗氧化活性的大小为2–30 nm的稳定铁纳米颗粒的生态生物合成,表明其可能的应用。
