What is nano silver?

Nano means an order of magnitude. A nanometre (nm) equals a billionth metre. Nano silver describes particles of metallic silver with a size of 1-100 nm in at least one dimension. Nano silver particles may form and degrade spontaneously in nature [1-4] or can be produced artificially [5-7].

The nano scale increases the surface per volume unit and thus leads to increased chemical, biological and catalytic activity. Due to the larger surface, more reactive silver ions can be released. The beneficial surface-volume-ratio leads to a higher effect at lower raw materials use. See frequently asked questions for more information.

Due to its special physicochemical properties and its high potential, nano silver enables new and innovative applications.
