Market forecast of Nano Sliver
Global Nano Silver Market was valued at $433 million in 2015, and is expected to reach $1,605 million by 2022, supported by a CAGR of 20.5%. Nano silver has at least one external dimension in the range of 1100 nanometers approximately. It is available in a number of physical and chemical forms such as metallic particles, silver ion, soluble silver compounds, and combinations that are available in solution, dispersion, colloidal, suspensions, and matrix of different substances (polymers, zeolites, and others).
The two main aspects that change the behavior of silver at nano scale are:
- Higher surface to volume ratio: the large surface area favors the formation of silver ions that enhance its antibacterial effect
- The mobility in the human body (and, in principle, in other biological media)
Nano silver particles are presumably capable of entering almost all human organs and penetrating cell membranes. This bioavailability could result in a potential impact on human health and environment, both in terms of hazard and exposure in the different biological media.
