Biomediated silver nanoparticles were synthesized with the aid of an eco-friendly biomaterial, namely, aqueous Tribulus terrestris extract. Silver nanoparticles were synthesized using a rapid, single step, and completely green biosynthetic method employing aqueous T. terrestris leaf extracts as both the reducing and capping agent. Silver ions were rapidly reduced by aqueous T. terrestris leaf extracts, leading to the formation of highly crystalline silver nanoparticles. An attempt has been made and formation of the silver nanoparticles was verified by surface plasmon spectra using an UV-vis (Ultra violet), spectrophotometer. Morphology and crystalline structure of the prepared silver nanoparticles were characterized by TEM (Transmission Electron Microscope) and XRD (X-ray Diffraction), techniques, respectively. FT-IR (Fourier Transform Infrared), analysis suggests that the obtained silver nanoparticles might be stabilized through the interactions of carboxylic groups, carbonyl groups and the flavonoids present in the T. terrestris extract.
采用一种环保型生物材料——蒺藜水提物,生物介导合成了银纳米粒子。使用快速、单步、完全绿色的生物合成方法,以蒺藜叶水提物作为还原剂和稳定剂,合成了银纳米粒子。银离子被蒺藜叶水提物迅速还原,形成了高结晶度的银纳米粒子。尝试使用紫外-可见(UV-Vis)分光光度计通过表面等离子体共振光谱来验证银纳米粒子的形成。通过透射电子显微镜(TEM)和 X 射线衍射(XRD)技术分别对制备的银纳米粒子的形貌和晶体结构进行了表征。傅里叶变换红外(FT-IR)分析表明,所得银纳米粒子可能通过存在于蒺藜提取物中的羧酸基团、羰基和类黄酮的相互作用而稳定。
