All of the grand goals for nanoscience are dependent upon reliable ways to fabricate nanostructures. The  challenges to nanofabrication are many, beginning with the incredibly broad range of applications, materials,  and geometries that have been proposed for nanoscale structures. Applications include nanoelectronics,  nanophotonics, nanomechanics, nanocatalysis, nanoantennae, and nanosensors, to name only a few. Materials  are needed that posess almost every conceivable range of properties: metallic to insulating, hard to soft, inert to  reactive, luminescent to quenched, crystalline to glassy - the list goes on. As a result, an immeasurable number  of elements, compounds, and alloys have been subject to nanostructuring and nanofabrication tools. Add to this  the range of geometrical nanostructures required: disks, rods, holes, pyramids, etc., and a range of tunability in  the degree of interaction between nanoparticles to be isolated or closely coupled. The degree of long range  ordering, either random or periodic, can also be a critical consideration, as well as whether that ordering  extends in one, two, or three dimensions. It is clear that nanofabrication is a daunting task.  The range of nanofabrication routes towards these structures is almost as diverse as the materials, applications,  and geometries needed for next-generation applications. The approaches can begin to be  compartmentalized by separation into either a ‘‘top-down’’ or ‘‘bottom-up’’ approach.
