Abstract
Today engineered nano-materials have attracted a great deal of attention due to their important properties which have given birth to vast technological and economic growth in a number of industrial sectors. Nano-materials are indeed expected to become the cornerstone of a number of sectors such as microelectronics, materials, textiles, energy, healthcare and cosmetic goods. Nanotechnology applications will give rise to cleaner energy production, lighter and more durable materials, inexpensive clean water production and will benefit medical applications such as smart drugs and diagnostics.
However, one has to be mindful of the risks involved concerning potential toxicity and exposure route and the verdict is still out on a number of nano-materials as to the relative dangers to humans and the environment.
This brief review hopes to describe some of the main contenders and their real world applications but it should only be considered a snapshot of the industry and its relative potential.
