Abstract Amorphous selenium nanoparticles have been synthesized by pulsed laser ablation in liquids. After undergoing a thermal treatment at 121°C for 60 minutes, the amorphous nanoparticles crystallized into trigonal ones. The antimicrobial properties of both amorphous and trigonal nanoparticles have been compared; and the amorphous ones displayed better antibacterial and antifungal properties compared to the trigonal ones. Specifically, Methicillin-resistant Staphylococcus aureus (MRSA), Ampicillin-resistant Escherichia coli, Pseudomonas aeruginosa, Staphylococcus epidermidis, and Candida albicans were almost completely inhibited in the presence of amorphous selenium nanoparticles at 0.025 microgram/ml concentrations after 24 hours of in vitro culture, compared to controls (no nanoparticles).

Abstract Novel nanocomposite structure has been made from physical mixing of polymer blend consist PMMA, PEO and PS filled with selenium nanoparticles. The nanocomposite had been deposited on glass slide by drop casting to form a thin film. This film was examined by required instrument like FESEM, XRD, EDS and UV-Vis to show the main physical properties of it. The XRD results were reflected the crystallinity nature of selenium NPs. SEM result shows the porosity nature of prepared film , where the pore size ranging from nano to micro size on all the surface of film. More >

Abstract Background: Nano-selenium has been widely used in antiviral and anticancer therapy, and has the advantages of good targeting and low toxicity. For the first time, we combined male reproduction with nano-selenium to investigate its antioxidant effect. This study investigated the protective effect of lentinan functionalized selenium nanoparticles on oxidative stress injury of the hydrogen peroxide (H₂O₂)-induced Leydig cell line, TM3. Methods: The suitable concentration of nano-selenium treatment to promote cell proliferation was also discussed. The concentration of 4 μM could significantly promote the growth of TM3 cells. Oxidative stress damage was caused using an 800 μM concentration… More >

Abstract A H₂O₂-induced oxidative stress injury cell model was established to investigate the antioxidant effect of nano-selenium on mouse spermatocyte lines and the regulation mechanism of the expression level and activity of selenium-containing antioxidant enzymes induced by oxidative stress. A safe and effective nano-drug system of functionalized selenium-containing nanoparticles (SeNPs) was developed with lentinan (LNT) (SeNPs@LNT). Mice spermatocyte line GC2-spg cells were treated with SeNPs@LNT (1, 2, 4, 8, 16, 32 μM) for 24–72 h to evaluate the cytotoxicity of selenium. GC2-spg cells were randomly divided into the following groups: control, hydrogen peroxide (H₂O₂), SeNPs@LNT, and H₂O₂+SeNPs@LNT groups.… More >
