The production methods of selenium nanoparticles

Abstract

In recent years, the application of selenium nanoparticles has been increasing in medicine, agriculture, engineering, and food science. Therefore, researchers are converting inorganic selenium sources into nano form by various methods. Particularly both probiotics and pathogenic bacterial strains have the ability to synthesize selenium nanoparticles under aerobic and anaerobic conditions. Amazingly, dose-dependent selenium nanoparticles have antibacterial activity against their own pathogenic producer, even when added externally. Also, plant extracts and conventional chemical reducing agents continue to make a significant contribution to the production of selenium nanoparticles in an economic, eco-friendly, simple, and rapid way. Biological and chemical methods are suitable for the biological applications of selenium nanoparticles such as functional food or nutritional supplements and nanomedicine.

Electrospun polymeric nanofibers for dental applications

“…Furthermore, owing to their properties like larger surface area, porosity, and flexibility, electrospun nanofibrous structures have become a pivotal constituent for future high‐performance electronic devices and sensors 185–196 . Electrospun scaffolds have also been investigated for use in agriculture, food industry, and water treatment 197–210 …”

Green synthesis of SeNPs using Sonchus maritimus based nanosized metal oxides for in vitro biological applications and in vivo acute toxicity evaluation

“…After color changing the reaction mixture was incubated with constant stirring in the dark at 130 rpm for 72°C to avoid photo-catalysis. When the solution color turns red, the samples were obtained by centrifugation, washed twice with distilled water and ethanol, dried, and stored in an ambercolored sample vial until use (KHANDSUREN and PROKISCH, 2021).…”

Microbial-Based Biotechnology: Production and Evaluation of Selenium-Tellurium Nanoalloys

“…Se-NPs can also be prepared using other reductions such as γ-radiolysis, chemical, and biological reduction [8]. Actually, bacterial and plant metabolites mainly cause the biological transformation of NPs, strengthening and enhancing the reduction process, which is the most effective as it is cheap, rapid, and highly pure [9]. Se-NPs have several important characteristics including small size, atomic arrangement, shape, complex internal structure, and high surface area-to-volume ratio.…”
