Nanotechnology is a branch of science that deals with particles 1-100 nanometers in size. Experts believe possible dangers of nanotechnology lie in how these tiny particles might interact with the environment, and more importantly, with the human body. Billions of dollars are being spent to incorporate nanoparticles into products that are already being marketed to the public; when this investment is compared to the the comparatively scant research into nanotech health issues, some scientists become concerned.

There are some hefty social concerns about nanotechnology too. Nanotechnology may also allow us to create more powerful weapons, both lethal and non-lethal. Some organizations are concerned that we'll only get around to examining the ethical implications of nanotechnology in weaponry after these devices are built. They urge scientists and politicians to examine carefully all the possibilities of nanotechnology before designing increasingly powerful weapons. If nanotechnology in medicine makes it possible for us to enhance ourselves physically, is that ethical? In theory, medical nanotechnology could make us smarter, stronger and give us other abilities ranging from rapid healing to night vision. Should we pursue such goals? Could we continue to call ourselves human, or would we become transhuman -- 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 ...more

Nanotechnology is a branch of science that deals with particles 1-100 nanometers in size. Billions of dollars are being pumped into incorporating nanotechnology. Many experts believe that possible dangers of nanotechnology lie within how these tiny particles may interact with the environment. Many experts say that elements encountered on the nanoscale behave differently than their larger counterparts. Here are some facts about nanotechnology that need some attention to:

1. Nobel-winning physicist Richard Smalley of Rice University discovered that carbon nanotubes and fullerenes, which are nanoparticles of carbon, react differently to the environment. These nanoparticles of carbon behave in ways differently and make their classification a potentially dangerous one.

2. In March 2004, environmental toxicologist Eva Oberdrster, Ph.D. conducted some tests with the Southern Methodist University in Texas. They found that there was extensive brain damage to fish that were exposed to full ...more

What if I make some nanobots which converts O3 or O2 into cyanide. I imagine that would be a pretty clear & present danger. Theoretically speaking, once u perfect nanobot technology, it would be possible to inject the nanobots into a dead body & animate him back 2 life, with an inquenchable thirst for human flesh...
