Synthesis and (I.R and TEM) Characterization of leafs and stem nanoparticles of Artemisia plant: Comparative study for the evaluation of Anti-bacterial efficiency

New nanoparticles of Artemisia plant extracts with Silver ions (Ag+) were synthesized, the particles were characterized by I.R and TEM images. Both of Stems and Leafs were selected in this study. The anti- bacterial investigation included Negative gram (E. Coli) and Positive gram (Staphylococcus). The results of I.R analysis showed presence different of functional groups of – OH, -C =O and Aromatic which explained of presence of varies compounds as phenols and Flavonoids in the nanoparticles. TEM images of nanoparticles exhibited that the nanoparticles in Nano scale of 0.12 -24 nm. The anti-bacterial studies showed that nanoparticles gave high inhibition zones comparing with plant extracts on the both E. coli and Staphylococcus species. But the effect nanoparticles gave more effective on E. Coli (Negative gram) bacteria comparing to Staphylococcus (positive gram), this result is harmony with some previous studies.
