Abstract:
Nanotech derives much of its power from transformations that occur when matter is reduced to the molecular dimension. For example, breaking down a chunk of a material into nanoparticles vastly increases its surface area, often by a factor of millions. This makes it dramatically more reactive -- quicker to ignite or melt and absorbing more faster. Think of a spoonful of confectioner's sugar dissolving instantly in a cup of coffee, while a sugar cube in another cup has barely begun to lose its sharp corners.
