Selenium is a trace and essential micronutrient for the health of humans, animals, microorganisms.

Nanoparticles hold great potential in contributing to high-resolution bioimaging as well as for biomedical applications. Although, selenium (Se) nanoparticles (NPs) have been investigated owing to their potential roles in therapeutics, the imaging capability of these NPs has never been explored. This manuscript identifies the intrinsic fluorescence of Se NPs, which is highly beneficial for nano...

Selenium is an essential trace element and is an essential component of many enzymes without which they become inactive. The Se nanoparticles of varying shape and size may be synthesized from Se salts especially selenite and selenates in presence of reducing agents such as proteins, phenols, alcohols and amines. These biomolecules can be used to reduce Se salts in vitro but the byproducts relea...

BACKGROUND Selenium is well documented to inhibit cancer at higher doses; however, the mechanism behind this inhibition varies widely depending on the cell type and selenium species. Previously, we have demonstrated that Bacillus licheniformis JS2 derived biogenic selenium nanoparticles (SeNPs) induce non-apoptotic cell death in prostate adenocarcinoma cell line, PC-3, at a minimal concentratio...

The last few decades have seen an overwhelming increase in the amount of research carried out on use inorganic nanoparticles. More fascinating is tremendous progress made chalcogen and chalcogenide nanoparticles cancer theranostics. These nanomaterials, which were initially synthesized through chemical methods, now been efficiently produced using different plant materials. paradigm shift toward...

Selenium (Se) is an element of growing environmental concern, because low aqueous concentrations can lead to biomagnification through the aquatic food web. Biofilms, naturally occurring microbial consortia, play numerous important roles in the environment, especially in biogeochemical cycling of toxic elements in aquatic systems. The complexity of naturally forming multispecies biofilms present...

There are wide spread bacterial contamination issues on various paper products, such as paper towels hanging in sink splash zones or those used to clean surfaces, filter papers used in water and air purifying systems, and wrappings used in the food industry; such contamination may lead to the potential spread of bacteria and consequent severe health concerns. In this study, selenium nanoparticl...

This study presents an ecologically conscious methodology for synthesizing tea polypeptides-selenium nanoparticles (TP-SeNPs) exhibiting antioxidant and antibacterial properties, utilizing polypeptides (TP). Proteins were extracted from leaves using alkali extraction-acid precipitation method, response surface (RSM) was employed to optimize the preparation processes both TP TP-SeNPs. The extrac...

Abstract In the present era, due to increasing incidence of environmental stresses worldwide, developmental growth and production agriculture crops may be restrained. Selenium nanoparticles (SeNPs) have precedence over other because significant role selenium in activating defense system plants. addition beneficial microorganisms, use biogenic SeNPs is known as an environmentally friendly ecolog...
