Selenium Nanoparticles (SeNP)

Glantreo’s highly monodispersed Selenium Nanoparticles (SeNP) are available in a number of sizes including, 250 and 300 nm diameters. Absorbance wavelengths of these SeNPs have  lambda max. values at  577 nm and 640 nm respectively. Absorbance at these wavelengths gives the SeNPs a strong red colour, which along with their  compatibility for passive protein conjugation, makes them ideal candidates for biological labelling applications, including lateral flow assays (LFA). Furthermore, the intrinsic fluorescence properties of Selenium nanoparticles allow them to be used in imaging applications. Finally, the anti-cancer, anti-bacteria and anti-fungal properties of selenium nanoparticles combined with their biological labelling properties place them in a unique position as a self-reporting therapeutic.
