green synthesis of silver nanoparticles:eco-friendly and antibacterial

nano world daily. in this paper the lens culinaris seed extract was assessed for thegreen synthesis of silvernanoparticlesat temperature of 25◦c. the nanoparticles were characterized using inductively coupledplasma spectrometry (icp), x-ray diffraction (xrd) and transmission electron microscopy (tem). thenthe antimicrobial activities of these nanoparticles were investigated. p. aeruginosa and s aureus were used as representatives of gram-negative and gram-positive bacteria, respectively. percentage conversion of metal ion to metal nanoparticles were more than 95% after 60 days of the reaction. xrd was used to confirm the crystalline nature of the particles. silver nanoparticles were mostly spherical with range in size from 5-25 nm. ag nanoparticles synthesized with extract were exhibited a strong antibacterial activity against bothp.aeruginosa and s.aureus.this process is completely green and eco-friendly compatible.
