Therapeutic applications of selenium nanoparticles

Biomedicine & 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

Journal 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

Micro & 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 ...

A randomized trial of selenium supplementation and risk of type-2 diabetes, as assessed by plasma adiponectin [PDF]

, 2012
Background: Evidence that selenium affects the risk of type-2 diabetes is conflicting, with observational studies and a few randomized trials showing both lower and higher risk linked to the level of selenium intake and status. We investigated the effect
