The synthesis, characterization and application of biologically synthesized nanomaterials have become important research areas in nanotechnology, and the green synthesis of nanoparticles using plants is being increasingly studied largely because this approach is considered to lack the problems associated with conventional synthesis. Here we report the synthesis and characterization (using a scanning electron microscope) of silver nanoparticles (AgNPs) obtained using extracts of leaves of the medicinal plants, Artemisia sieberi and Calotropis procera. Scanning electron microscopy (SEM) studies revealed the characteristics of the synthesized nanoparticles which were confirmed by analyzing the excitation of surface plasmon resonance (SPR) using UV–vis spectrophotometer at 482 nm. SEM analysis of the synthesized Ag NPs clearly showed that the particles were predominantly spherical in shape, mostly aggregated and having a size around 8–20 nm. Finally, we consider that the nanoparticles synthesized in this study have potential for wide application in nanotechnology and nanomedicine. https://www.biotech-asia.org/vol14no2/synthesis-of-silver-nanoparticles-from-artemisia-sieberi-and-calotropis-procera-medical-plant-extracts-and-their-characterization-using-sem-analysis/ Artemisia sieberi; Calotropis procera; Green synthesis; Silver nanoparticles; SEM analysis
