Nanoparticles bio production, considering their performance in medicine and biological
science, is increasing; also, raising awareness of green chemistry and bioprocesses has
encouraged the use of environmentally friendly methods for the production of non-toxic
nanomaterials.. Also uses of plant extracts are found to be more advantageous over chemical,
physical and microbial (bacterial, fungal, algal) methods for silver nanoparticles (AgNPs)
synthesis. The objectives of this study were the production of silver nanoparticles using aqueous and
hydroalcoholic extracts of Avena sativa L. an investigation of the effect of extracts on the
synthesis of nanoparticles. The morphology and size of the nanoparticles were determined
using Scanning Electron Microscope (SEM) and UV-Vis spectroscopy. SEM images showed that
the synthesized nanoparticles were mainly spherical and round shaped. The results indicated
that synthesized nanoparticles using an aqueous extract were better than the synthesized
nanoparticles using hydro-alcoholic extract in shape and size.
Synthesize silver nanoparticles using Avena sativa L. Extract provides environmentally friendly
option as compared to currently available chemical/ physical methods.
