Comparative analysis of antibacterial activity of Silver nanoparticles synthesized using leaf extract of wheat varieties

In present study, it has been reported the biological synthesis of silver nanoparticles (agnps) using aqueous leaf extract prepared using hot percolation treatment of wheat varieties (pbw343, triticum durum and aegilops tauschii )for the reduction of silver ions to silver nanoparticles. bioreduction of ag^+ to ag˚ was observed when an aqueous extract of wheat leaves augmented with silver nitrate (agno3) was incubated for 2 hours at 100 ˚c. the formation of silver nanoparticles was con rmed by surface plasmon resonance as determined by uv-vis spectra at 430 nm. silver nanoparticles of size ranging from 5-14 nm of spherical shape were characterized using transmission electron microscopy (tem). these nanoparticles were found to possess potential antibacterial activity against (escherichia coli, staphylococcus aureus, klebsiella) using disc diffusion method and macro dilution (tube) broth method. this environmental friendly method provides a simple, easy, fast and cost effective method for nanoparticles synthesis and can be used in several areas of medicines and industries
