Selenium nanoparticles

Selenium nanoparticles are used in research areas of various biomedical applications due to their biocompatibility, bioavailability, and low toxicity. Our aqueous dispersion of 350 nm Se nanoparticles are suitable to use in diagnostic assay development including lateral flow assays and staining. For example, 350 nm Se nanospheres were reported to achieve a lower limit of detection in a lateral flow device than gold nanoparticles.

We produce aqueous dispersions of selenium nanoparticles with a particle size of 350 nm and high chemical purity. These selenium nanoparticles exhibit strong absorption at 695 nm, resulting in a bright red color.
