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.
