Ethics are an important part of a scientific development that one cannot overlook. While some will look at technological capabilities and potential profits, others must consider the impact that the technology has on society and our world. This is the case in the development of nanotechnology, and concerns about ethics in Nanotechnology are increasing.

There are many positive ventures highlighted here, with social and medical benefits. Some are now concerned about what could happen if nanotech moves into other industries, and into the wrong hands.

Are these concerns justified, and should we pay more attention to who is using this tech?
