Özet

Metallic nanoparticles (NPs) are widely used in biomedical, agricultural, and environmental industries. With their high surface area to volume ratio, they support biological and  hemical processes to advance more efficiently at the nanoscale. Among these nanoparticles, silver nanoparticles come forward for their use in different areas, especially for their antimicrobial properties. They have advantages over nanoparticles such as gold and platinum due to their cheaper cost and wide wavelength range in which they exhibit plasmonic band properties. Biological nanoparticle synthesis based on the reduction of metals by biological molecules comes forward due to its features, such as less toxicity, less cost, and less synthesis time compared to other methods. This method allows using a wide range of organisms, from bacteria to plants, for the synthesis of nanoparticles. Anchusa azurea is a medicinal plant and a member of the Boraginaceae family. It grows in high places above sea level and blooms in June-July. As a result of chemical analyses, it contains many phytochemicals such as flavonoids and alkaloids. It is used as an anti-inflammatory and antidiuretic in traditional medicine. In this study, silver nanoparticles were synthesized using the water extract of the leaves of A. azurea. A. azurea was collected from its natural habitat. After the plant was cleaned and dried, the leaves were separated and ground. The water extract of A. azurea leaves was prepared by adding water at 80C and incubating for 30 minutes. Following the extract reaching room temperature, small drops of 1mM AgNO3 solution were added. The color change from greenish to brownish indicated the formation of AgNPs. The presence of these NPs was also verified by UV-Vis with a peak at 428 nm. The characterization of AgNPs synthesized from A. azurea leaves will be completed by further analyses such as SEM, XRD, and FTIR.
