For the past decade, so-called nanotechnology has been all the rage in the manufacturing community as well as in marketing to consumers. Nanotechnology is a manipulation of matter on an atomic, molecular and supramolecular scale. Nanotubes are a type of nanoparticle that can be used as an electrical conductor or insulator and can be large enough to create piping through which other nanoparticles can be channeled.
A recent study from Cell press published in Science Daily, has found that some of these nanotubes can cause mesothelioma in mice. This is significant because mesothelioma is a very rare cancer that is currently believed to be caused virtually exclusively by exposure to deadly asbestos fibers. This could be a major public health crisis because while asbestos is being used and less, the nanotechnology industry is exploding.
While the popular science fiction movies of the 1990s commonly depicted nanotechnology as involving tiny robots that perform all sorts of functions at a microscopic level, real science is nowhere near that level sophistication. Current nanotechnology involves the use of materials that are so small they are measured using a nanoscale, and we are talking about microscopic materials. Continue reading
