“…SeNPs can be synthesized by physical, chemical and biological routes. 4,6,7 Methods of biological synthesis of SeNPs are less toxic, ecofriendly and cost-effective, and yield stable SeNPs which do not aggregate because of a protein coating over them. 8,9 However, the activity of these SeNPs has not been compared with chemically synthesized SeNPs.…”

The aim of this study was to synthesize selenium nanoparticles (SeNPs) using cell suspension and total cell protein of Acinetobacter sp. SW30 and optimize its synthesis by studying the influence of physiological and physicochemical parameters. Also, we aimed to compare its anticancer activity with that of chemically synthesized SeNPs in breast cancer cells. Cell suspension of Acinetobacter sp. SW30 was exposed to various physiological and physicochemical conditions in the presence of sodium selenite to study their effects on the synthesis and morphology of SeNPs. Breast cancer cells (4T1, MCF-7) and noncancer cells (NIH/3T3, HEK293) were exposed to different concentrations of SeNPs. The 18 h grown culture with 2.7×10 9 cfu/mL could synthesize amorphous nanospheres of size 78 nm at 1.5 mM and crystalline nanorods at above 2.0 mM Na 2 SeO 3 concentration. Polygonal-shaped SeNPs of average size 79 nm were obtained in the supernatant of 4 mg/mL of total cell protein of Acinetobacter sp. SW30. Chemical SeNPs showed more anticancer activity than SeNPs synthesized by Acinetobacter sp. SW30 (BSeNPs), but they were found to be toxic to noncancer cells also. However, BSeNPs were selective against breast cancer cells than chemical ones. Results suggest that BSeNPs are a good choice of selection as anticancer agents.

“…The results revealed that some cations including Mg 2+ and Ca 2+ interfere with the CL system. This problem was solved by passing real water sample solutions containing gentamicin through a cation-exchanger column (43). Based on the results (Table 6), even 250-fold Mg 2+ and Ca 2+ do not interfere with gentamicin determination after this preliminary step.…”

Flow‐injection chemiluminescence determination of gentamicin: optimization by central composite design

et al. 2013

A simple and sensitive flow-injection chemiluminescence (CL) method has been developed for the determination of gentamicin sulfate. The method is based on the inhibitory effect of gentamicin on the CL emission accompanying oxidation of luminol by H2 O2 in an alkaline medium in the presence of Cu(II) as a catalyst. Inhibition was caused by the formation of a strong complex between analyte and the catalyst. Experimental variables, including the concentrations of luminol (µmol/L), H2 O2 (mol/L), Cu(II) (mol/L) and NaOH (mol/L), were optimized using a central composite design. Under optimum conditions, the plot of CL intensity versus gentamicin concentration was found to have two linear ranges. One range was at low concentrations from 1.0 to 10.0 mg/L and the other was from 10.0 to 30.0 mg/L. Precision was calculated by analyzing samples containing 5.0 mg/L gentamicin (n = 11) and the relative standard deviation (RSD) was 1.7%. Also, a high injection throughput of 120 samples/h was achieved. This method was successfully applied to the determination of gentamicin sulfate in pharmaceutical formulations and water samples.

“…16,17 Additionally, elemental selenium nanoparticles exhibit low cytotoxicity compared with selenite (SeO 22 3 ) and selenate (SeO 22 4 ), and show anticancer and therapeutic features that enable them to be employed in numerous medicinal applications. 3,26 Nonetheless, both chemical and physical approaches have drawbacks in the synthesis, such as high temperature and pressure, acidic pH of the medium, both harsh and sometimes expensive chemicals and most disturbingly toxic by-products. [20][21][22] Selenium nanoparticles can be synthesized using different approaches, from physical methods, such as laser ablation, 23,24 ultraviolet radiation, 25 and hydrothermal techniques, to chemical methods, such as acid decomposition, catalytic reduction, and precipitation.…”

Antimicrobial resistance is a global concern that affects more than two million people each year. Therefore, new approaches to kill bacteria are needed. One of the most promising methodologies may come from metallic nanoparticles, since bacteria may not develop a resistance to these nanostructures as they do for antibiotics. While metallic nanoparticle synthesis methods have been well studied, they are often accompanied by significant drawbacks such as cost, extreme processing conditions, and toxic waste production since they use harsh chemicals such as corrosive agents (hydrazine) or strong acids (hydrochloride acid). In this work, we explored the environmentally safe synthesis of selenium nanoparticles, which have shown promise in killing bacteria. Using Escherichia coli, Pseudomonas aeruginosa, Methicillin-resistance Staphylococcus aureus, and S. aureus, 90-150 nm average diameter selenium nanoparticles were synthesized using an environmentally safe approach. Nanoparticles were characterized using transmission electron microscopy, energy dispersive X-ray spectroscopy to determine the chemical composition, and inductively coupled plasma mass spectrometry to validate chemistry. Nanoparticles were also characterized and tested for their ability to inhibit bacterial growth. A decay in bacterial growth after 24 h was achieved against both S. aureus and E. coli at biogenic selenium nanoparticle concentrations from 25 to 250 µg/mL and showed no significant cytotoxicity effect against human dermal fibroblasts for 24 h. Bacteria were able to synthesize selenium nanoparticles through the use of different functional structures within the organisms, mainly enzymes such as selenite reductases. Therefore, biogenic selenium nanoparticles made by bacteria represent a viable approach to reduce bacteria growth without antibiotics overcoming the drawbacks of synthetic methods that employ toxic chemicals. © 2018 Wiley Periodicals, Inc.
