Is Nanotechnology Healing or Enhancing? Scientists today do not understand where the line is drawn between enhancing and healing. There is no way to distinguish when healing stops and enhancing begins. For this they should both be treated equally that way nanotechnology can be brought in. Other scientists argue that there can be a distinguished marker telling when therapy is enhancement. They say that restoring the functionality is only therapy and everything else is considered enhancing. But other scientists counter argue that it is not enhancing but it is also evolution. (7)
Should we pursue such goals? Could we continue to call ourselves human, or would we become transhuman? Is it the next step on man's evolutionary path? Since almost every technology starts off as very expensive, would this mean we'd create two races of people, a wealthy race of modified humans and a poorer population of unaltered people? (8) |  We are currently learning new things about nanotechnology every day but first we need to learn more about materials and their properties at the nanoscale. Universities and corporations across the world are rigorously studying how atoms fit together to form larger structures. Elements at the nanoscale behave very differently than they do in their bulk form, there's a concern among scientists that some nanoparticles could be toxic. Some doctors worry that the nanoparticles are so small, that they could easily cross the blood-brain barrier and poison the world. If we plan on using nanoparticles to coat everything from our clothing to our highways even to medicine, we need to be sure that they won't poison us. (8)
