Abstract

Nickel nanoparticles were synthesized by biosynthesis method with the help ocimum sanctum leaf extract. The properties of nickel nanoparticles were characterized by using various techniques viz. UV-Visible spectrophotometer, Fourier transform infrared spectrometry(FTIR) and scanning electron microscopy(SEM) coupled with energy dispersive micro analysis(EDAX) and XRD. The spectroscopic methods confirmed the formation of nickel nanoparticles and the microscopic technique confirmed the shape and size of the nickel nanoparticles as spherical. Antibacterial activity of the synthesized nanoparticles was measured by zone inhibition method. The nickel nanoparticles showed effective antibacterial activity against human pathogenic bacteria such as Pseudomonas, Aeruginosa and Escherichia coli. The usage of plant extract for the biosynthesis of nickel nanoparticle makes the process cost effective, non-hazardous and green method.
柞蚕叶提取物生物合成纳米镍及表征
采用生物合成的方法,以菟丝子叶提取物为原料合成纳米镍。采用紫外可见分光光度计、傅里叶变换红外光谱(FTIR)、扫描电镜(SEM)、能谱分析(EDAX)和x射线衍射(XRD)等技术对纳米镍的性能进行了表征。光谱学方法证实了镍纳米颗粒的形成,显微技术证实了镍纳米颗粒的形状和大小为球形。采用带抑制法测定了合成的纳米颗粒的抑菌活性。镍纳米颗粒对假单胞菌、铜绿菌和大肠杆菌等人类致病菌具有良好的抑菌活性。利用植物提取物生物合成纳米镍,具有成本效益、无公害、绿色环保等特点。
