Green synthesis and characterization of silver nanoparticles using Scrophularia Striata extract

2019 Eurasian Chemical Communications  
Here, green synthesis of silver nanoparticles (NPs) using aqueous extract of Scrophularia Striata was demonstrated. In order to obtain the best formation conditions of NPs, different physicochemical parameters such as volume of the extract, silver ion concentration, temperature and reaction time were studied. Synthesized resultant NPs were characterized using UV, SEM, TEM, EDX, XRD, FT-IR and DLS analyses. A color change to brown after adding the extract to the silver nitrate solution was

Plants have been used as stabilizing and reducing agents for NPs, due to their antioxidant properties and many secondary compounds.
