Novel Method Synthesizing Colloidal Silver Nano Particles Using Lecithin

Abstract Silver nanoparticles were synthesized and stabilized by a simple and environment friendly method in a nanoliposomes structure. Nanoliposomes were prepared by facing lecithin to the aqueous phase solutions while stirring vigorously. In this method, the lecithin concentration to silver nitrate ratio (KLec/Ag = [Lecithin]/ [AgNO3]) is the influencing factor in synthesis of silver nanoparticles. The influence of the factor on the stability, size distribution, and antibacterial properties of synthesized silver nanoparticles were studied by UV-visible, dynamic light scattering (DLS), and antibacterial assay. The UV spectra indicated a single symmetric extinction peak at 400 nm confirming spherical shape of the synthesized silver nanoparticles. A high KLec/Ag value leads to reducing the intensity of extinction spectra and size of Ag-liposomes nanoparticles. The stabilized silver nanoparticle with various lecithin concentrations showed a good antibacterial activity against Staphylococcus aureus a gram positive bacterium and Eschericia coli a gram negative bacterium.
