Introduction
Today, nanotechnology is one of the most widely used fields of science and nanotechnology in the world (1). In addition, this interdisciplinary field is applied in the field of physics, electronic materials, biology, agriculture, chemistry and medicine, which uses these scientific fields to control matter at the molecular scale (2). The utilization of medicinal plants for the synthesis of nanoparticles is a relatively uncomplicated and cost-effective approach (3,4) and one of the advantages of this method is non-toxicity (5). The green synthesis method of metal ions using plant compounds is usually a one-step reaction that transforms into nanoparticles without the need for stabilizing agents. Biologically active substances and compounds in plant extracts such as flavonoids and other effective water-soluble active metabolites can cause the reduction of metal ions and the formation of nanoparticles at room temperature (6). generally, green chemistry is a research or innovation method that includes a practical part for the design, development, and efficient production of products that can minimize hazardous substances for health (7). Nanoparticles have special features like size, shape, and morphology, and for this reason, they are widely used in human life. Among them, metal nanoparticles such as silver, gold, platinum, and palladium are widely used by physicians and are healthy (8). Among the various nanoparticles synthesized, AgNPs are recognized as one of the most extensively employed nanotechnologies in disease treatment. A significant amount of research has been conducted on their potential anticancer (9), antibacterial (10), antifungal (11), and antiviral (12) effects. However, silver alone may have limited properties or play a minor role (13). Hera et al. discovered that Ag can be produced from alfalfa biomass aqueous solution that is pH-dependent (14). biosynthesis of silver nanoparticles by plants such as aqueous and alcoholic extracts of Aloe vera (15), the leaf extract of South African artemisia (Afra Artemisia) (16), aqueous extract of aerial part of Corniculum Glaucium (8), plant felt leaf extract of Abutilon Indicum (L.) Sweet (17) And many other plants have been done. Many reports exist about the use of synthesized silver nanoparticles and their antibacterial properties. For example, the results of the studies of Aziziyan Sharmeh et al. Nanoparticles are synthesized using an aqueous extract from the Sambucus nigra plant (18). Heidarzadeh et al. green synthesis of silver nanoparticles Extracted by Citrus aurantium extract (19) and in the study of Sheikh Rafi et al., nanoparticles were synthesized by Origanum Majorana extract (20) and it was shown that these nanoparticles inhibit the growth of E coli. and S aureus. bacteria. polygonum aviculare L. is a member of the family Polygonaceae-Dock. This plant grows in Africa, Europe, Asia, and especially the Middle East. The aforementioned plant species is used to manage diarrhea, homeostasis and wound healing. In addition, it acts as a diuretic and helps eliminate kidney stones (21). It has been confirmed that this plant has high amounts of antioxidants. This research involved the initial use of Polygonum aviculare L. extract for the eco-friendly production of silver nanoparticles. Subsequently, UV-Vis spectroscopy was utilized to verify the creation of these nanoparticles., and Morphological investigation by TEM, FE-SEM, XRD, and FT-IR to examine functional groups in nanoparticles and investigation of antioxidant properties of silver nanoparticles produced by DPPH assay and investigation of their antibacterial properties by Disk Diffusion method.
