Nanotechnology deals in the realm of the nearly invisible. The word comes from the Greek nanos, meaning “dwarf”. But by most accounts, the tech-nology’s potential is anything but small. Scientists and engineers can now physically work with materials at the atomic level to create stain-proof fabrics, scratch-resistant paints and longer-lasting tennis balls. And researchers say new medical diagnostic tools and smaller, more efficient fuel cells and batteries based on nanoscience are on the way.
From computer chips invisible to the naked eye to microscopic machines that seek out and destroy cancers inside the human body, a lot of scientists argue that the potential of nanotechnology could be endless, but not without controversy.
“If we can get a nanoparticle into a cell, that might prove to be a new and useful drug delivery device,” says Ms. Kulinowski, Executive Director of the Center for Biological and Environmental Nanotechnology at Rice University. “ On the other hand, it might prove to be a toxin to the cell either by punching a hole in the cell membrane or otherwise disrupting the cell’s function”.
Whether the benefits of nanotechnology outweigh the risks will determine the future of what many researchers hope will be the world’s next industrial revolution.
