![]() Of the more than 1000 consumer products that claim to contain nanomaterials, more than a quarter of them contain nanosilver. The remarkably strong antimicrobial activity is a major reason for the recent increase in the development of products that contain nanosilver. Due to the properties of silver at the nano level, nanosilver is currently used in an increasing number of consumer and medical products. Silver has been known to be a potent antibacterial, antifungal and antiviral agent, but in recent years, the use of silver as a biocide in solution, suspension, and especially in nano-particulate form has experienced a dramatic revival. Nanomaterials are nanoparticles that have special physicochemical properties as a result of their small size (Buzea et al., 2007). Due to the properties of silver at the nanoscale, nanosilver is nowadays used in an increasing number of consumer and medical products. Nanoparticles are classified solely based on their size, and may or may not exhibit size-related properties that differ significantly from those observed in bulk materials (ASTM, 2006 Buzea et al., 2007). Nanomaterials (such as nanotubes and nanorods) and nanoparticles are particles that have at least one dimension in the range of 1 to 100 nm. The physical and chemical properties of nanomaterials can become very different from those of the same material in larger bulk form. When a solid material becomes very small, its specific surface area increases, which leads to an increase in the surface reactivity and quantum-related effects. Nanotechnology takes advantage of the fact that ![]() In nanotechnology, a nano particle is defined as a small object or particle that behaves as a whole unit in terms of its transport and properties. Silver has long been used as a disinfectant for example, the metal has been used in treating wounds and burns because of its broad-spectrum toxicity to bacteria as well as because of its reputation of limited toxicity to ![]() One of the most beneficial uses of silver has been as a potent antibacterial agent that is toxic to fungi, viruses and algae. ![]() It is used as a precious commodity in currencies, ornaments, jewelry, electrical contacts and photography, among others. Silver has been valued throughout history for many of its properties that are useful to humans. ![]()
