The present study used physics to synthesize silver nanoparticles using aqueous extract of fresh garlic as reducing and as a stabilizing agent silver nitrate solution. This method has proven to be environmentally friendly and safe for the synthesis of stable silver nanoparticles. The acquisition of silver nanoparticles was confirmed by optical detection, that is, by changing the color of the liquid to transparent orange and then blackish brown. Then, the characterization was confirmed using other assays. In this study, it was found that the absorption peak of silver nanoparticles was at a wavelength of 420 nm and the particle size ranged between [50–350] nm. The surface roughness of silver oxide/silver nanoparticles was 9.32 nm with an average square roughness of 21.19 nm, and the energy dispersive spectra showed that the absorption peak was in the region of 3 keV, indicating that the nanoparticles contained crystalline silver. In this study, the stability of the silver nanoparticles was good, as ZP reached (− 19.5). The results confirm that the conductivity increases with the increase in frequency due to the high energy of the photons, which causes the electrons to vibrate in the energy levels and thus increase the energy in the mitochondria and increase the movement of sperm in the Diabetic mice treated with doses of silver nanoparticles. The toxic effect of silver nanoparticles has been evaluated in other studies, in addition to evaluating antioxidants, antifungals, treating cancer cells, regulating cholesterol levels, the effect of these nanoparticles on sex cells in pregnant female mice, heart tension, and many other tests. In this study, the activities and efficacy of silver nanoparticles on sperms were determined in male mice with diabetes caused by STZ, and the treatment period was long (35 days) so that the evaluation period was a complete life cycle of male sex cells and within a long period of time and at an average nano size. This has not been studied in other previous studies. The results indicate that the biosynthesis of silver nanoparticles using garlic plant led to positive results on sperm treatments by contributing to an increase in the number of sperm with reactivation and a decrease in abnormalities in addition to a decrease in mortality due to diabetes. This is evidence that the synthesis of silver nanoparticles using garlic plant size (50–350 nm) can treat impotence and be used in the future in the treatment of many diseases without side effects.

“…XRD is an essential device for revealing the crystallographic structure, phase, and key lattice parameters of a structure through the obtained diffraction pattern. Many materials can be explored by XRD, such as metals, metal oxides, polymers, thin films, and nanocomposites [ 70 , 71 ]. Figure 4 elucidates the diffraction patterns of the synthesized silver nanoparticles in the Ag-BBE and Ag-PPE samples.…”

A comparative study was applied to investigate the potential of Callistemon citrinus (bottlebrush) flower extract (BBE) and Punica granatum (pomegranate) peel extracts (PPE) for the sustainable synthesis of the silver nanoparticles, Ag-BBE and Ag-PPE, respectively. The synthesis process of Ag NPs using the selected extracts was applied under optimized conditions. Hence, the effect of the selected plant’s type on the different characteristics of the synthesized green Ag NPs was investigated. The UV-Vis spectroscopy revealed the presence of the characteristic silver peaks at 419 and 433 nm of the Ag-BBE and Ag-PPE, respectively. The XRD spectra reported the fcc phase formation of Ag NPs. The TEM results highlighted the morphological features of the synthesized Ag NPs. with a size range of 20–70 nm, and with 10–30 nm for Ag-BBE and Ag-PPE, correspondingly. The Raman spectra revealed characteristic silver bands in the Ag-PPE and reflected some bands related to the natural extract in the Ag-BBE sample. The antimicrobial activity and statistical analysis investigation were conducted against four selected oral pathogens (Staphylococcus aureus (SA), Candida albicans (CA), Staphylococcus epidermidis (S. epi), and Enterococcus faecalis (EF)). Both tested extracts, BBE, and PPE, revealed potential effectivity as reducing and capping agents for Ag NP green synthesis. However, the synthesized NPs demonstrated different features, depending on the used extract, reflecting the influence of the plant’s biomolecules on the nanoparticles’ properties.
