You may have heard that the future lies with nanotechnology - the manufacture of materials and machines on a microscopic scale - but wonder how this relates to a sustainable future. This month, leading U.S. scientists will explore just that at the annual American Chemical Society meeting in Atlanta, Georgia. As part of a new GreenNano initiative, they will present environmentally-friendly applications of nanotechnology manufacturing processes and explore how nanotech can be used to heal environmental damage.
