Biogenic selenium nanoparticles produced by ATCC 393 inhibit colon cancer cell growth and .

Selenium compounds exhibit excellent anticancer properties but have a narrow therapeutic window. Selenium nanoparticles, however, are less toxic compared to other selenium forms, and their biogenic production leads to improved bioavailability. Herein, we used the probiotic strain ATCC 393, previously shown to inhibit colon cancer cell growth, to synthesize biogenic selenium nanoparticles.
