Resumen
The article comments on the adverse and beneficial effects of nanotechnology revolution. Nanotechnology can be defined as the manipulation, precision placement, measurement, modeling, or manufacture of sub-100 nanometer scale matter. The greatest risk to human health and to the environment lies in this rapid expansion of different types of nanoparticles under development and the potential for their production. It brings with it the possibility of large-scale human exposure predominantly in the work place as these nanoparticles are incorporated into products of every conceivable type from Information Technology to food. Another critical area where nanoparticles might cause potent harm is in medicines. Nanoparticles that reach the bloodstream can affect the blood clotting system. The medical uses of nanoparticles are discussed. The medical applications of nanoparticles have involved utilizing the knowledge of the human body and how it changes during disease, coupled with processes that alter the nanoparticle surface properties allowing the particles to reach key areas of the body.
