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.

“…These taxa are belonging to the Crassulaceae family [ 5 ]. Recently, we discussed the use of the leaves and aerial parts of plants as a natural source of bioactive compounds used for the biosynthesis of silver nanoparticles (AgNPs) [ 6 ]. In this context, we have chosen an extremophile plant species to research new biogenic AgNPs.…”

The present paper described the first green synthesis of silver nanoparticles (AgNPs) from the extremophile plant Aeonium haworthii. The characterization of the biosynthesized silver nanoparticles was carried out by using UV-Vis, FTIR and STM analysis. The antioxidant, antidiabetic and antimicrobial properties were also reported. The newly described AgNPs were spherical in shape and had a size of 35–55 nm. The lowest IC50 values measured by the DPPH assay indicate the superior antioxidant behavior of our AgNPs as opposed to ascorbic acid. The silver nanoparticles show high antidiabetic activity determined by the inhibitory effect of α amylase as compared to the standard Acarbose. Moreover, the AgNPs inhibit bacterial growth owing to a bactericidal effect with the MIC values varying from 0.017 to 1.7 µg/mL. The antifungal action was evaluated against Candida albicans, Candida tropicalis, Candida glabrata, Candida sake and non-dermatophytic onychomycosis fungi. A strong inhibitory effect on Candida factors’ virulence was observed as proteinase and phospholipase limitations. In addition, the microscopic observations show that the silver nanoparticles cause the eradication of blastospores and block filamentous morphogenesis. The combination of the antioxidant, antimicrobial and antidiabetic behaviors of the new biosynthesized silver nanoparticles highlights their promising use as natural phytomedicine agents

“…FTIR spectra can be used to detect the presence of specific functional groups in plant extracts during different analytical procedures. Peaks detected at 1 017, 2 914, and 3 350 cm −1 indicate the presence of the C-O bond of ether, H-C-H bond of alkanes, and N-H bond, respectively [46].…”

Excessive utilization of nanoparticles renders it necessary to produce safer and more secure nanoparticles while preserving their efficacy. In this study, Psidium guajava L. pulp extract-mediated silver nanoparticles (AgNPs) were synthesized, characterized, and further evaluated regarding their antioxidant potential. The green synthesized silver nanoparticles (G-AgNPs) showed a higher level of radical scavenging activity (RSA) (25.85%), hydrogen peroxide scavenging activity (34.34%), and ferric reducing power (0.28). The comparison of the control group (G1) with the various treatment groups (G2-G6) revealed that the levels of catalase (CAT), superoxide dismutase (SOD), and glutathione-S-transferase (GST) were significantly different (P < 0.05). The levels of blood urea, uric acid, blood urea nitrogen (BUN), serum glutamic pyruvic transaminase (SGTP), serum creatinine, serum glutamic-oxaloacetic transaminase (SGOT), alkaline phosphatase, total bilirubin, and serum electrolytes were also evaluated. The results of clinical biochemistry also strengthened our hypothesis that G-AgNPs are less toxic than C-AgNPs. Finally, the histopathology of liver, kidney, and intestinal tissues indicated that green-synthesized AgNPs are relatively safer.
