In situ Synthesis of Metal Selenide Nanoparticles by Selenium Nanoparticle Disproportionation

open access: yes, 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)

Therapeutic applications of selenium nanoparticles

open access: yesBiomedicine & Pharmacotherapy, 2019
Nanoparticles (NPs) serve to reduce the toxicity, enhance bioactivity, improve targeting, and provide versatile means to control the release profile of the encapsulated moiety. Among different NPs, inorganic NPs of metals like Ag, Au, Ce, Fe, Se, Ti and Zn possess a significant place owing to their unique bioactivities in nanoforms. Selenium (Se) is an

Toxicity of repeated oral intake of organic selenium, inorganic selenium, and selenium nanoparticles: A review

open access: yesJournal of Trace Elements in Medicine and Biology, 2023
To protect from toxicity at supra-essential doses of selenium, it is important to determine dose levels at which adverse effects occur.We identified relevant literature on the repeated dosage of selenium and extracted dose descriptors on reported endpoints, except on genotoxicity/carcinogenicity.Selenium forms with toxicological data were organic ones:

Mycosynthesis of selenium nanoparticles

open access: yesMicro & Nano Letters, 2011
The culture filtrate of the fungus, Alternaria alternata, was used for the bio-reduction of sodium selenate to produce selenium nanoparticles. Change in colour to dark red of the reaction mixture signifies the development of nano-α-selenium. Dynamic light scattering experiments, atomic force microscopy, scanning and transmission electron microscopic ...
