“…Recently, nanocomposites are widely used for treating resistant microbes, which produce slim biolms. 74,75 Previous studies have reported that RGO nanosheets, RGO nanolms and RGO paper have potential antibacterial activity against spherical and rod-shaped bacteria with low cytotoxicity. 76,77 Therefore, the RGO-NiO, RGO-AgO, and RGO-ZnO nanocomposites were synthesized in this study.…”

“…In the current study, the supernatant of Bacillus megaterium ATCC 55000 was used to synthesize Se-NPs. The process of selenious acid reduction was monitored, while the cell-free extract changed from colorless to reddish color [53,54]. The UV-visible spectrum of Se-NPs synthesized indicated that it had maximum absorption at (0.860 abs) and 435 nm.…”

Rhizoctonia root-rot disease causes severe economic losses in a wide range of crops, including Vicia faba worldwide. Currently, biosynthesized nanoparticles have become super-growth promoters as well as antifungal agents. In this study, biosynthesized selenium nanoparticles (Se-NPs) have been examined as growth promoters as well as antifungal agents against Rhizoctonia solani RCMB 031001 in vitro and in vivo. Se-NPs were synthesized biologically by Bacillus megaterium ATCC 55000 and characterized by using UV-Vis spectroscopy, XRD, dynamic light scattering (DLS), and transmission electron microscopy (TEM) imaging. TEM and DLS images showed that Se-NPs are mono-dispersed spheres with a mean diameter of 41.2 nm. Se-NPs improved healthy Vicia faba cv. Giza 716 seed germination, morphological, metabolic indicators, and yield. Furthermore, Se-NPs exhibited influential antifungal activity against R. solani in vitro as well as in vivo. Results revealed that minimum inhibition and minimum fungicidal concentrations of Se-NPs were 0.0625 and 1 mM, respectively. Moreover, Se-NPs were able to decrease the pre-and post-emergence of R. solani damping-off and minimize the severity of root rot disease. The most effective treatment method is found when soaking and spraying were used with each other followed by spraying and then soaking individually. Likewise, Se-NPs improve morphological and metabolic indicators and yield significantly compared with infected control. In conclusion, biosynthesized Se-NPs by B. megaterium ATCC 55000 are a promising and effective agent against R. solani damping-off and root rot diseases in Vicia faba as well as plant growth inducer.

“…The presence of Se-NPs connected to starch is confirmed by a red-shift of about 5 cm −1 for OH stretching vibration as well as the band at 763 cm −1 [49]. Additionally, a very clear band of Se-NPs at 643 cm −1 is noticed in the spectrum which is characterized for the spherical shape of Se-NP [50][51][52].…”

Melamine and its analogues are illegally added to falsify the content of protein in food products.The elevated concentrations of these compounds cause harmful effects in humans and animals. In this contribution, the potential ability of synthesized starch-stabilized selenium nanoparticles (Se-NPs@starch) towards inhibiting the toxicity of melamine on the liver and kidneys has been systematically investigated. The Se-NPs@starch were characterized by XPS analysis, EDS mapping analysis, TEM, and FT-IR. Starch plays a crucial role in the stabilization and dispersion of Se NPs, as noticed from the TEM and EDS investigations. Furthermore, the atomic ratio of Se distribution over starch surface is approximately 1.67%. To evaluate the activity of Se-NPs@starch, this study was conducted on four groups of adult male rats. Group I (the control group), group II received Se-NPs@starch, group III received melamine, whereas group IV received melamine and Se-NPs@starch. The results reveal a significant alteration in the histoarchitecture of both hepatic and renal tissues induced by melamine. While melamine induces severe toxic effects on the hepatic and renal tissues, the administration of Se-NPs@starch results in remarkable protection of rats against melamine-induced toxicity. Collectively, the affordable starch-stabilized Se-NPs have a potent biological activity, making them auspicious candidates for biomedical applications.
