Nanostructured films, dispersions, high surface area materials, and supramolecular assemblies are the high utility intermediates to many products with improved properties such as solar cells and batteries, sensors, catalysts, coatings, and drug delivery systems. They have been fabricated using various techniques. Nanoparticles are obvious building blocks of nanosystems but, require special techniques such as self-assembly to properly align the nanoparticles. Recent developments have lead to air resistant, room temperature systems for nanotemplates with features as small as 67 nm.39 More traditionally, electron-beam systems are used to fabricate devices down to 40 nm.40 http://www.sigmaaldrich.com/materials-science/nanomaterials/tutorial.html#Intermediates
