results the results of energy-dispersive x-ray demonstrated that the purified nps consisted of only se. in addition, transmission electron micrographs showed that 120- to 140-nm spherical se nps were the most common. an antifungal assay was performed with a standard clinical and laboratory standards institute broth microdilution method. minimum inhibitory concentration (mic) measurements of the...

The goal of the present work is to fabricate selenium nanoparticles utilising Morinda citrifolia leaves extract via green approach. UV-Vis spectroscopy, FT-IR, and TEM were used characterise nanoparticles. size generated SeNPs in was anticipated be 12-160 nm based on images. antioxidant activity NPs discovered 66.7 83.7% free radical inhibtion. When concentration rises, viability cancer cells d...

Selenium, as an important trace element, is part of selenoproteins with growth-modulating properties and multifactorial mechanisms action. The biological effects Se depend on the dose chemical form in which it enters body. Selenium nanoparticles have unique characteristics, including small size, large surface area, solubility multifunctionality. inclusion phytonutrient-functionalized feed exped...

Wetting properties of biomaterials, in particular nanomaterials, play an important role, as these influence interactions with biological elements, such as proteins, bacteria, and cells. In this study, the wetting phenomenon of titanium substrates coated with selenium nanoparticles was studied using experimental and mathematical modeling tools. Importantly, these selenium-coated titanium substra...

A full-field hard-x-ray microscope at SSRL has successfully imaged samples of biological and environmental origin at 40 nm resolution. Phase contrast imaging of trabeculae from a female mouse tibia, loaded in vivo to study the effects of weight-bearing on bone structure, revealed a complex network of osteocytes and canaliculi. Imaging of cordgrass roots exposed to mercury revealed nanoparticles...

Abstract In recent years, the importance of nanomaterials in food science, medicine, etc. has been increasing quickly. Herein, organic and inorganic red selenium nanoparticles synthesised by reduction sodium selenite with chemical biological reducing agents. Grey hexagonal form aqueous powder was assembled at a high temperature 85 °C for 10 min. Also, enriched yogurt made that contained about 2...

Herein, we present the formation of cadmium selenide (CdSe) islands embedded in a porous structure of entangled selenium (Se) nanofibers in the host matrix of a room temperature ionic liquid (RTIL). Electron beam irradiation has been employed to initiate the formation of the nanostructure while RTIL simultaneously played the role of a solvent, stabilizer and a shape guiding template for such mo...

A H2O2-induced oxidative stress injury cell model was established to investigate the antioxidant effect of nano-selenium on mouse spermatocyte lines and regulation mechanism expression level activity selenium-containing enzymes induced by stress. safe effective nano-drug system functionalized nanoparticles (SeNPs) developed with lentinan (LNT) (SeNPs@LNT). Mice line GC2-spg cells were treated S...

Grams of copper selenides (Cu(2-x)Se) were prepared from commercial copper and selenium powders in the presence of thiol ligands by a one-pot reaction at room temperature. The resultant copper selenides are a mixture of nanoparticles and their assembled nanosheets, and the thickness of nanosheets assembled is strongly dependent on the ratio of thiol ligand to selenium powder. The resultant Cu(2...
