An Organic Acid-induced Synthesis and Characterization of Selenium Nanoparticles [PDF]

Journal of Nanotechnology, 2011
A simple wet chemical method has been developed to synthesize selenium nanoparticles (size 40–100 nm), by the reaction of sodium selenosulphate precursor with different organic acids in aqueous medium, under ambient conditions. Polyvinyl alcohol has been

Selenium Nanoparticles Selectively Target KRAS G13D to Inhibit Colorectal Cancer. [PDF]

Adv Sci (Weinh)
The mechanisms of SeNPs therapy in cancer treatment, encompass three parallel actions: (1) seleno‐amino acids, key metabolites, upregulate GPX2 expression, thereby inhibiting tumor metastasis via the GPX2‐HIF1α‐VEGF signaling pathway; (2) selenite (SeO32−), an inorganic metabolite, forms hydrogen bonds with amino acid residues 13–17 of the KRAS G13D ...

In situ Synthesis of Metal Selenide Nanoparticles by Selenium Nanoparticle Disproportionation [PDF]

, 2023
Amorphous Selenium Nanoparticles (α-SeNPs) exist in a metastable state of polymeric Se8 rings and Sen chains that break and reform by electron propagation. Here we show that this quality can underlie the formation of metal selenide nanoparticles (MSeNPs)

Metabolic‐Redox Remodeling of Inflammatory Synovium by Mannose‐Modified Selenium Nanoparticles for Osteoarthritis Therapy [PDF]

Advanced science
Elevated GLUT1‐driven glycolysis and disrupted selenoprotein‐dependent redox homeostasis drive osteoarthritic progression. Intra‐articular mannose‐modified selenium nanoparticles (M‐SeNPs) selectively target hypermetabolic synovial cells to reprogram aberrant glycolysis and restore endogenous antioxidant defenses.
