Streszczenie

whole-gooseberries1Plants and crops as renewable and cheap resources to produce nanomaterial. In recent years the use of plant extracts for nanoparticles production is an alternative to chemical and physical methods. Silver nanoparticles are widely used for health care and it’s green synthesis is studied in this research. Phytochemical fabrication of silver nanoparticles from AgNO3 solution was done using aqueous extract of Salvia limbata, an endemic herb of Iran. The plant was dried at ambient temperature. The extraction was performed with deionized boiled water. Synthesized silver nanoparticles were characterized by means of ultraviolet-visible spectroscopy, infra-red spectroscopy and X-ray diffraction spectroscopy and transmission electron microscopy. To confirm the formation of silver nanoparticles, the ultraviolet- visible absorption spectrum was obtained. Surface plasma resonance absorption at 420-450 nm showed that silver nanoparticles were formed. The average size of obtained silver nanoparticles was found to be 2-25 nm in face center cubic crystalline structure.
