FTIR analysis was performed to classify the biomolecules in Pedalium murex which were responsible for reduction of the metals and for the stabilization of nanoparticles. If current flows through a workpiece, even a hard metal can be machined [57]. Asp., 256, 111 https://doi.org/10.1016/j.colsurfa.2004.12.058. 707, 46. After 20 min, the color of the solution (leaf extract + Ag+) changed from light yellow to dark brown, indicating the formation of AgNPs.

This method is limited because of large space occupied by the tube furnace, great amount of energy consumption by the furnace while raising the environmental temperature around the source material and a lot of time required achieving thermal stability [42].

The general method of synthesizing silver nanoparticles in chemical reduction is as colloidal dispersions in water or organic solvents (Sharma et al. Among all the nano-products, 313 products (23%) are impregnated with nano-sized silver. Metal nanoparticles have a high specific surface area and surface atoms, because of their outstanding physicochemical characteristics, including optical, catalytic, electronic, magnetic and antibacterial properties. It is suggested that the surface of the nanoparticles is negatively charged and dispersed in the medium.

An aqueous solution (0.01 mM) of silver nitrate (AgNO3) and various concentrations of leaf extract from 1 to 5 ml were prepared separately. Nat. Appearances of these peaks are due to the presence of phytochemical compounds in the leaf extracts.

Silver contained materials are used for surgical meshes. In certain conditions, the particles could be prepared as small as 100 nm [17]. (2016) , Adv. 2013).

It is well known that silver nanoparticles can be produced by chemical reaction at low cost with high yield. [80] have prepared AgNPs using white grape pomace aqueous extract (WGPE) as both reducing and capping agent, Laura et al., [81] had biosynthesized silver nanoparticles using Murraya koenigii (curry leaf) extract as the reduction and stabilizing agent.

EDAX analysis of silver nanoparticles was performed on a SUPRA55 (CARL ZEISS, Germany) using FESEM equipped with an EDAX attachment. Synthesis of metal nanoparticles is enormous due to their potential applicability in different areas such as electronics, chemistry, energy, and medicine development (Saxena et al. 8 (11), pp. J. Phys. Sci. 49. J. 3441. This is one of the advantages of nanoparticles synthesized using plant extracts over those synthesised using chemical methods. In principle, any collection of atoms bonded together with a structural radius of < 100 nm can be considered a nanoparticle [6].
