Currently, the interest in synthesis of metallic nanoparticles has increased a lot because these systems are suitable to be used distinct fields such as medical, pharmaceutical, agricultural, environmental protection, etc. Their can done using different agents bacteria, fungi, and yeasts or plant extracts fresh plants. This paper aims synthesize silver (AgNPs) selenium (SeNPs) Stellaria media (...

A novel nitrate- and selenite reducing bacterium strain ZYKT was isolated from a rice paddy soil in Dehong, Yunnan, China. Strain ZYKT is a facultative anaerobe and grows in up to 150, 000 ppm O2. The comparative genomics analysis of strain ZYKT implies that it shares more orthologues with B. subtilis subsp. subtilis NCIB 3610T (ANIm values, 85.4-86.7%) than with B. azotoformans NBRC 15712T (AN...

Given their low toxicity and natural presence in the human diet, selenium nanoparticles have been established as potential candidates for the treatment of numerous cancers. Red-allotrope selenium nanoparticles (rSeNPs) were synthesized and characterized in this study. Head and neck squamous cell carcinoma (HNSCC) and human dermal fibroblast (HDF) cells were cultured and exposed to rSeNPs at con...

Abstract As an alternative to antibiotics, nanoparticles are increasingly being employed target bacteria. Nanotechnology has the potential revolutionize treatment of bacterial infections. Biosynthesis is becoming popular as a cutting-edge method for producing functionally diverse Nanoparticles with enormous therapeutic potential. Various biological resources have already proven their ability ma...

Background: Many studies have been conducted in the field on effects of industrial and chemical antibacterial substance abuse human health also resistance a wide range bacterial species to antibiotics. Sea cucumber is one important aquatic animals which has therapeutic nutritional properties. The purpose this study investigate effect selenium nanoparticles sea extract Staphylococcus aureus, Kle...

Extensive research on the nutritional and medical application of selenium nanoparticles (SeNPs) was performed in past decades. Besides nutritional values, new characteristics such as antibacterial and anticancer properties depict a bright future for high Selenium (Se) consumption in the coming years. Se is essential for the proper functioning of most of the m...

This work investigates the potential for harnessing the association of bacterial proteins to biogenic selenium nanoparticles (SeNPs) to control the size distribution and the morphology of the resultant SeNPs. We conducted a proteomic study and compared proteins associated with biogenic SeNPs produced by E. coli to chemically synthesized SeNPs as well as magnetite nanoparticles. We identified fo...

Selenium nanoparticles (SeNPs) with a bright red colour have aroused worldwide attention due to their unique properties in selenium supplementation because of low toxicity and favourable bioavailability. A simple method was developed for making nanolayer on the inner surface Polyvinyl chloride (PVC) silicone tube. The were produced by reaction sodium selenite ascorbic acid. Red amorphous been s...
