“…On the other hand, in SeNPs, the band at 560 cm −1 corresponds to the out-of-plane bending vibrations of the aromatic C-H groups [ 28 ], which, according to Stella et al [ 29 ], originate from the stretching vibrations of the metal–oxygen bond. Likewise, the band at 772 cm −1 was found in SeNPs, as indicated by Jahdaly et al [ 30 ], andsuggests the binding of SeNPs to the -OH groups present in AsAc, giving rise to Se-O coordination bonds between Se and AsAc. The Se–OH interaction nature could be due to the binding of the SeNPs to the C=O groups of the AsAc oxidation products, forming a layer around the SeNPs to avoid their agglomeration [ 13 ].…”

The use of selenium nanoparticles (SeNPs) in the biomedical area has been increasing as an alternative to the growing bacterial resistance to antibiotics. In this research, SeNPs were synthesized by green synthesis using ascorbic acid (AsAc) as a reducing agent and methanolic extract of Calendula officinalis L. flowers as a stabilizer. Characterization of SeNPs was performed by UV-vis spectrophotometry, infrared spectrophotometry (FTIR), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), and transmission electron microscopy (TEM) techniques. SeNPs of 40–60 nm and spherical morphologies were obtained. The antibacterial activity of marigold extracts and fractions was evaluated by disk diffusion methodology. The evaluation of SeNPs at different incubation times was performed through the colony-forming unit (CFU) count, in both cases against Serratia marcescens, Enterobacter cloacae, and Alcaligenes faecalis bacteria. Partial antibacterial activity was observed with methanolic extracts of marigold leaves and flowers and total inhibition with SeNPs from 2 h for S. marcescens, 1 h for E. cloacae, and 30 min for A. faecalis. In addition, SeNPs were found to exhibit antioxidant activity. The results indicate that SeNPs present a potentiated effect of both antimicrobial and antioxidant activity compared to the individual use of marigold extracts or sodium selenite (Na2SeO3). Their application emerges as an alternative for the control of clinical pathogens.

“…The third stage, which runs from 350 • C to about 450 • C, is the most fragmented and has the greatest weight loss behavior. The curve trend shows a 1.7% weight loss up to 200 • C, probably due to unpredictably developing matter (primarily adsorbed with humidity), and its losing weight appears to be nearly complete after 467 • C. This could be attributed to the vaporization of SeNPs caused by N2 flowing through the system [63]. 3.2.4 TEM, particle size with zeta potential, and SEM-EDX The development of polydispersed SeNPs with sizes ranging from 21.7 to 83.6 nm was revealed by TEM investigation of colloidal solution (Figure 3A).…”

Background/Goal/Aim: Plant extract is affordable and does not require any particular conditions; rapid production of nanoparticles using plants offers more advantages than other approaches. Selenium nanoparticles (SeNPs) have received much attention in the last decade due to SeNPs diverse and different applications. Herein, this study aimed to biosynthesize SeNPs using aqueous extract of Urtica dioica leaf through green and ecofriendly method. Moreover to fully characterize SeNPs using different techniques, and to evaluate it for antimicrobial activity as well as anticancer activity.Main Methods and Major Results: SeNPs were biosynthesis using aqueous leaf extract of U. dioica (stinging nettle). The biosynthesized SeNPs were characterized using UV-visible spectroscopy (UV-Vis), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy dispersive electron spectroscopy (EDX), transmission electron microscopy (TEM), and thermalgravimetric analysis (TGA). Antimicrobial and anticancer activities of biosynthesized SeNPs were assessed. Results illustrated that SeNPs exhibited promising antibacterial activity against Gram-positive and Gram-negative bacteria, as well as unicellular and multi-cellular fungi. Moreover, minimal-inhibitory concentration (MIC) of

“…Also, the deterioration in bacteria's cell wall is based on the interaction of AgNPs with DNA, enzymes, and proteins involved in the metabolic pathway of bacteria, causing significant metabolism to stop and death [73]. In our system, AgNPs are associated with triggering the activation of reactive oxygen species (ROS) abundance, leading to oxidative stress, lipid peroxidation, protein oxidation, and DNA damage [74]. Figure 9b is a simple diagram representing the possible pathway of AgNPs while tackling the cell wall of bacterial species.…”

It is well known that biogenic synthesis, as compared to other processes, has proven to be highly effective in the fabrication of silver nanoparticles (AgNPs). Thus, our current study focused on synthesizing AgNPs using coffee waste extract (CWE). CWE contains many compounds identified by HPLC, which reduce, cap, and stabilize AgNPs in its solution. The as-synthesized AgNPs were produced with a monodispersed small size around 20 nm and exhibited in-plane dipole plasmon resonances of hexagonal nanoplates. AgNPs were characterized by both physical and spectroscopic methods, which confirmed their nanoscale dimensions with a hexagonal shape. The as-prepared AgNPs (12 mg) enabled the photodegradation of phenol compounds (20 mL) with a removal efficiency of ~ 94.6% in a short time in the presence of citric acid. Additionally, the second promising application of AgNPs was the tendency to remove the hazard 2,4 dinitroaniline (2,4 DNA) with a percent more than 97% while using only 7 mg of AgNPs. Moreover, the green synthesized AgNPs are superior in inhibiting bacterial growth and killing most infected microbes such as B. subtilis , P. aeruginosa , S. aureus , and E. coli . The electrochemical characteristics of the AgNPs were evaluated using a three-electrode system. The calculated specific capacitance was 280 F g −1 at 0.56 A g −1 . Furthermore, after 1000 cycles at 2.2 A g −1 , the AgNPs electrode demonstrates an excellent cycling stability behavior with 94.8% capacitance retention. Based on the previous promising results, it can be concluded that CWE is an environmentally benign extract to prepare AgNPs with low cost, saving and easily used for many great domains in photocatalytic, phenol compound removals, and production of functional nanodevices.
