ABSTRACT
Lotfi SA, Fazeli M, Zolghadr AR, Namazi F, Sardo HS., Synthesis
and characterization of Juglans rejia resin
aqueous extract silver nanoparticles and antibacterial effects, Onl J Vet Res., 24 (3):166-174, 2020. We synthetized silver nanoparticles with Juglans rejia resin
aqueous extract. The effect of different concentrations of silver nitrate and resin
for production of nanoparticles was detected by spectrophotometery
at λmax of 482 nm. Particles were
monitored by emission scanning electron microscopy and X-ray diffraction. By electron scan imaging we found hexagonal
shaped nanoparticles 25-35 nm suggesting reduction of silver ions by resin
extract. By X-ray diffraction we found sharp Bragg peaks of elemental silver at
2◦ diffraction peaks at 38.1 ̊, 44.2 ̊, 64.4 ̊ and 77.4
̊ in 2θ, matching Joint Committee on Powder Diffraction standard 040783.
By disc diffusion, we determined effect of J. rejia
resin, nanoparticles with resin and empty particle controls on bacteria. Particles
with resin mildly inhibited E. coli, P. aeruginosa and S. aureus but not B.
subtilis whereas J. rejia resin did not
elicit any inhibition.
Keywords: Silver nanoparticles, Juglans rejia, antimicrobial.
