Health is wealthPossible Dangers of Nanotechnology
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. Complicating the dangers of nanotechnology, size and shape of nanoparticles affect the level of toxicity, preempting the ease of uniform categories even when considering a single element. In general, experts report smaller particles are more bioactive and toxic. Their ability to interact with other living systems increases because they can easily cross the skin, lung, and in some cases the blood/brain barriers. Once inside the body, there may be further biochemical reactions like the creation of free radicals that damage cells.
Nanotechnology should not be confused with molecular nanotechnology (MNT) a still theoretical science dedicated to manufacturing products from the atom up through use of nanoscale machines.
