==Nanofabrication==

There are ways of creating a piece of nanotechnology. The 'Top Down' method involves taking a larger object and removing parts to create a smaller structure similar to creating a statue from a block of stone. An example of a top down method is 'Electron Beam Lithography'. 'Bottom Up' nano technology means assembling a object from smaller parts, similar to building a statue out of Lego. An example of a bottom up method is 'Molecular Self Assembly'<ref>http://it.toolbox.com/wiki/index.php/Top-down_Approach_to_Nanotechnology</ref> <ref>Fundamentals of Microfabrication: The Science of Miniturization,Marc J.
