Those exposed to high risks are employees from different manufacturing plants producing nano particles products. Consequently, there have been calls for the regulation of the nano industry including the publishing of safety precautions to help those involved in the industry (Bowman and Hodge 2006)
Electronically, functional approach of nano technology seeks to create components of desired work regardless of their assembly. Here Molecular electronics develops electronic molecules usable as components in nano electronic devices (Das, et al
Nanotechnology has many challenges, hence, caution must be observed in the process The Need for Nanotechnology This technology, allows faster manufacture of lighter, stronger, safer and cleaner products. Nano technology unveils new products able to solve new problems in unimaginable ways yet with greater impact (Merkle 2000)
In addition, there are enormous cost implications in adding nano particles in products that are already being marketed to the public; this investment, compared to the comparatively scant research into nanotech issues, raises concerns. Evidence suggest that smaller particles are more bioactive and toxic (Shetty 2005)
