“…In this context, the presence of Se-bearing NPs in the sample was investigated by single particle (SP)-ICP-MS and transmission electron microscopy (TEM). SeNPs have gained considerable interest recently owing to their antioxidant, antimicrobial, and anticancer properties [63].…”

Selenium (Se) was found to inhibit the growth of the yeast Candida utilis ATCC 9950. Cells cultured in 30 mg selenite/L supplemented medium could bind 1368 µg Se/g of dry weight in their structures. Increased accumulation of trehalose and glycogen was observed, which indicated cell response to stress conditions. The activity of antioxidative enzymes (glutathione peroxidase, glutathione reductase, thioredoxin reductase, and glutathione S-transferase) was significantly higher than that of the control without Se addition. Most Se was bound to water-insoluble protein fraction; in addition, the yeast produced 20–30 nm Se nanoparticles (SeNPs). Part of Se was metabolized to selenomethionine (10%) and selenocysteine (20%). The HPLC-ESI-Orbitrap MS analysis showed the presence of five Se compounds combined with glutathione in the yeast. The obtained results form the basis for further research on the mechanisms of Se metabolism in yeast cells.

“…Compared to physicochemical protocols of NP synthesis, biological green synthesis of Se-NPs has elevated eco-friendly, non-toxic and biosafety advantages [10]. From the biological green synthesis agents, the employment of plant extracts in NP synthesis (phytosynthesis) is reported to be a simple, effectual and cost-effective method, compared to other biosynthesis agents involving microorganisms and enzymes [11].…”

Selenium (Se) as a bioactive micronutrient could be augmented via transforming into nanoparticles (NPs), especially using biogenic protocols, for usage as an antimicrobial element. The reducing power of costus (Saussurea costus) root extract (SCE) was employed for phytosynthesis of Se-NPs through a simple and rapid protocol that included stirred mixing of 10 mM Na2SeO3 with 1.0% SCE solution for 4 h. The phytosynthesized SCE/Se-NP composite was obtained with a mean diameter of 6.13 nm and a zeta potential of −42.8 mV. Infrared analyses revealed the involvement of many SCE phytogroups in Se-NP synthesis, whereas transmission microscopy displayed well distribution and spherical shapes of the phytosynthesized NPs. The antibacterial assessments against foodborne pathogens (Escherichia coli, Salmonella typhimurium and Staphylococcus aureus) revealed the superior powers of SCE/Se-NPs and the elevated potentialities of SCE and Se-NPs for inhibition of bacterial pathogens. The scanning micrographs indicated that SCE/Se-NPs were attached to bacterial cells and led to their complete lysis/explosion with exposure prolongation. The SCE/Se-NP composites are recommended for the effective control of foodborne bacterial pathogens, applying a simple and eco-friendly phytosynthesis protocol.

“…Selenium, a trace element, is known as essential poison for the human body, and its high amounts in the diet can be lethal and its low amount can be resulted in a chronic and decreasing body deficiency system [1]. Selenium nanoparticles (Se NPs) have high surface-to-volume ratio with more specific biological, chemical, physical, and pharmaceutical attributes and have attained much interests [2].…”

Selenium nanoparticles (Se NPs) were fabricated with propolis hydro-alcoholic extract and six different methods, namely, hydrothermal, microwave irradiation, ultrasonication, UV radiation, self-assembling, and conventional heating. Results indicated that antioxidant activity, turbidity, pH, and brix values of the provided hydroalcoholic propolis extract were 85.8%, 2.235% a.u., 4.1, and 3.2°Bx, respectively. Gas chromatography analysis revealed that approximately 38 bioactive compounds were detected in the provided extract within 40 min of retention time, including chalcone. Results also revealed that each method had advantage in fabrication of Se NPs compared to others, but spherical Se NPs with overall appropriate physicochemical attributes of particle size (50–60 nm), polydispersity index (0.362), zeta potential (−41.8 mV), maximum broad absorption peak (321 nm), and antioxidant activity (12.4%) were synthesized using the ultrasonication method with a frequency of 20 kHz and a power of 300 W for 10 min.
