Scientific Community Skeptical about Effects of Nanosilver on Environment

Advances in nanoscience, which relates to the field of study and manipulation of a number of chemical and biological substances in their nanoform – with dimensions in the range of 1-100 nanometers, have significantly affected several industries in the past few years. Several nanomaterials have found uses in a number of fields of medicine, technology, science, drug delivery, food, personal care applications and others owing to their unique physico-chemical properties.

In the field of medicines, nanomaterials are projected to be used in ways that will allow the detection of diseases at much earlier stages. Nanomaterials are also said to have the potential of solving one of the most critical and long standing issue before the pharmaceutical industry – delivering proper dosages of particular active agent at the site of a disease. In the food industry, nanomaterials have already started entering the field of food packaging and preservation. In the future, nanomaterials are expected to be used to improve the quality, safety, shelf life of food products as well as to examine contaminations in food products or packaging materials. Nanotechnology is expected to extend its reach to all major industries in the coming few years.
 
However, as these technologies and the use of several nanomaterials is new, the scientific world is a bit skeptical about their impact on the health of human beings and the environment. Nanosilver, one of the discoveries of nanotechnology, is also facing some troubles owing to this skepticism.

Nanosilver are said to have the ability of invading bacteria and other microorganisms and destroy them. They are widely used in a large range of consumer products such as sportswear, vacuums, toys, washing machines, suncreens, textiles, and others.

However, as with most other nanomaterials, the long term impact of nanosilver on humans and the environment are not known completely. Some recent studies have demonstrated that when laundered, the textiles impregnated with nanosilver released the material in the wash cycle and eventually in the environment. Nanosilver is said to pose difficulties for the growth of certain microbes that are essential for ecological systems.
