Merck, 938297-2ML, Selenium nanoparticles

General description
We produce aqueous dispersions of selenium nanoparticles with a monodisperse particle size of 40 nm and high chemical purity. These selenium nanoparticles exhibit strong absorption at 565 nm, resulting in a bright red color, which makes them ideal for staining or as a label in lateral flow applications. Furthermore, selenium (Se) nanoparticles possess remarkable properties such as high photoconductivity, along with significant piezoelectric, thermoelectric, and nonlinear optical responses.We produce aqueous dispersions of selenium nanoparticles with a monodisperse particle size of 40 nm and high chemical purity.

Application
Selenium nanoparticles (SeNPs) present higher biocompatibility and lower cytotoxicity than organic or inorganic Se compounds. Selenium nanoparticles have been studied for many therapeutic areas such as cancer, diabetes, Alzheimer′s disease and inflammation-related diseases, such as rheumatoid arthritis. Our 0.15wt% aqueous dispersion of 40 nm selenium nanoparticles are suitable to use in studies of therapeutic areas including treatment of fungal, bacterial, and parasitic infections, cancer, and diabetes. They can be used for targeted delivery of drugs, as contrast agents in medical imaging, and in the development of new therapeutic approaches. Due to its high photoconductivity and low melting point, it possesses great catalytic activity towards organic hydration and oxidation reactions.They have a narrow band gap (~1.7 eV), high absorption coefficient and mobility, which suits to be used as an absorber for high bandgap thin film solar cells. Selenium nanoparticles can be incorporated into solar cell technologies, specifically in the fabrication of thin-film solar cells or dye-sensitized solar cells.
