NGL may be the key to commercializing nanotechnology.

The article reports that nanotechnology promises a broad range of future applications in a wide variety of disciplines. Whether the topic is precision engineering, electromechanical engineering, mainstream biological and chemical sciences, or medical research, the two fundamentally different approaches to creating nanodevices are "top-down" and "bottom-up." Top-down refers to making nanoscale structures with machining and etching techniques; bottom-up applies to building organic and inorganic structures atom-by-atom or molecule-by-molecule.
