Nanotechnology - a lot of hype over almost nothing?

Article Excerpt
Nanotechnology involves the design, characterization, production and application of structures, devices and systems by controlling shape and size at nanometer scale (one billionth of a meter). The convergence of numerous scientific fields at the nano-scale is an exciting and rapidly progressing field of study. The applications of nanotechnology are infinite and have the potential to positively impact the lives of many, although negative effects are certain to arise and cannot be ignored.

Some argue that nanotechnology does not raise any novel ethical, economic, environmental, legal or social issues. Whether this is true or not, nanotechnology is certain to exacerbate and complicate these same issues. (1) Despite the exciting innovation that nanotechnology may bring, it is in danger of being derailed by negative public sentiment. The media and public action groups have published alarmist headlines and tales of caution for the promising technology. The ETC Group in particular has gone so far as to recommend a full-scale moratorium on any commercial production of new nanomaterials until the possible risks and dangers are fully researched and examined. (2) Thus, it is important for the ethical, environmental, economic, legal, and social issues surrounding nanotechnology to be examined and addressed appropriately (NE3LS issues). (3) Numerous reports, and papers prepared by government bodies, public action groups, NGOs, and academics from around the world have been released that express concern about nanotechnology. The most salient matters from these works have been grouped into different categories for further consideration and are as follows: (4)
