This study describes the biosynthesis of silver nanoparticles (AgNPs) using () leaf extract. The biosynthesized AgNPs were characterized by UV-Vis spectroscopy, Fourier transform infrared spectroscopy (FTIR), dynamic light scattering (DLS), X-ray diffraction (XRD), Raman spectroscopy, transmission electron microscopy (TEM) and scanning electron microscopy with (SEM-EDS). The AgNPs showed an average size of 10-20 nm, spherical shape, and crystalline nature. The application of these synthesized AgNPs to dye degradation showed that the AgNPs removed the two organic pollutants methylene blue (MB, 93.47%) and congo red (CR, (78.57%). investigation of the antifungal activity of the AgNPs against , a phytopathogenic fungus, showed a maximum percent radial growth inhibition of 82.00 ± 1.00% and a spore percent inhibition of 73.66 ± 3.94 for 150 μg/ml of biosynthesized AgNPs.
本研究描述了使用()叶提取物生物合成银纳米颗粒(AgNPs)的过程。通过紫外可见光谱、傅里叶变换红外光谱(FTIR)、动态光散射(DLS)、X射线衍射(XRD)、拉曼光谱、透射电子显微镜(TEM)和扫描电子显微镜(SEM-EDS)对生物合成的AgNPs进行了表征。AgNPs的平均尺寸为10-20纳米,呈球形且具有晶体性质。将这些合成的AgNPs应用于染料降解表明,AgNPs去除了两种有机污染物亚甲基蓝(MB,93.47%)和刚果红(CR,78.57%)。对AgNPs对植物病原真菌的抗真菌活性进行研究表明,对于150μg/ml的生物合成AgNPs,最大径向生长抑制率为82.00±1.00%,孢子抑制率为73.66±3.94%。
