    Nanotechnology Jeremy Rifkin wrote, in his article Biotech Century: Playing Ecological Roulette with Mother Natures Design, "Humans have been remaking the Earth for as long as we have had a history." Well the path of history humans have chosen to take also affects how we remake the Earth. In Neal Stephensons novel, The Diamond Age, one is shown how the technology of the time reshapes the political, economical and educational aspects of history. That technology is the manipulation of molecules

    Ethics of Nanotechnology Nanotechnology is actually a fairly new idea. This may not seem like any big deal in terms of ethics, but just like any type of scientific advancement there are positives and negatives. Of course the ethical issues don’t stem out of just the fact that this is a new kind of science. It branches off of “what will this new scientific technology be used for?” For example, Embryonic Stem Cell research. It’s not the research that’s bad it’s how they get the cells. There are

    Since 1959 that the concept of nanotechnology had been introduced to the American Physical Society meeting by Richard Feynman, it has been developed and applied into versatile areas (Azeredo, 2009). To define nanomaterial or nanostructure, this material must have at least one dimensional particle size about 1–100 nm (Duncan, 2011). It can be composite materials, ceramics, metals or polymeric materials (Hickman, 2002). A nanometer scale material can change the physical and chemical properties of
