Nanosilver production has been estimated at 2.8–20 tons per year in the United States 36 and 250–312 tons worldwide. 37 Volpe says this represents a minor component of overall silver production—estimated by the silver industry to exceed 31,250 tons 37 —and of silver volumes in the environment.

One nanomaterial that is having an early impact in healthcare product is nano-silver. Silver has been used for the treatment of medical ailments for over 100 years due to its natural antibacterial and antifungal properties. The nano silver particles typically measure 25nm.

Silver nanoparticles are nanoparticles of silver of between 1 nm and 100 nm in size. [1] While frequently described as being 'silver' some are composed of a large percentage of silver oxide due to their large ratio of surface to bulk silver atoms. Numerous shapes of nanoparticles can be constructed depending on the application at hand.

Nanosilver plays an important role in nanoscience and nanotechnology, and is becoming increasingly used for applications in nanomedicine. Nanosilver ranges from 1 to 100 nanometers in diameter. Smaller particles more readily enter cells and interact with the cellular components.

Nano silver is one of the most widely used engineering nanomaterials with antimicrobial activity against bacteria, fungi, and viruses. However, the widespread application of nano silver preparations in daily life raises concerns about public health.
