Abstract
Selenium sulfide, in analogy with selenium dioxide, is often considered as SeS2. At closer inspection, however, selenium sulfide represents a large family of rather complicated molecules which differ depending on the mode of preparation. Together, these compounds share extraordinarily low solubility in virtually any solvent with a biological activity rather impressive for such simple molecules. The surface reactivity of such microscopic and nanoscopic materials, prepared chemically or by fermentation, may provide an answer to this riddle and explain activities by a combination of physical, redox, metal binding, covalent, and non-covalent interactions with biomolecules and cells.
