Nanoism in New Era

Nanotechnology covers a wide range of materials and techniques With the development of semiconductors, bringing computers down to palm-size, scientists, telecommunication, medicine, biotechnology environmental energy, and universe security of which the risks and unknowns vary greatly. Nano material may pass easily into the bloodstream when inhaled or swallowed, and possibly when applied to the skin. Once inside the body, they seem to have access to most or all tissues and organs, including the brain. It is unknown whether nano materials can pass from a pregnant woman´s blood circulation to the fetal circulation or through breast milk to a nursing infant. These data demonstrate that inhalation of nano-size chemical pollutants is associated with asthma attacks, heart disease, strokes, and respiratory disease. At this stage it is useful to present the arguments of the enthusiasts who project the revolutionary potential of nano science and nanotechnology and those of the skeptics who seem to question the revolutionary potential Paper describes that how nano is everywhere.
