Nanostructures and Nanofabrication

Interest in nanotechnology is growing rapidly. Now it is possible to arrange atoms into structures that are only a few nanometers in size. A nanometer is about four atom diameters or 1/50000 of a human hair. Your fingernails grew about a nanometer while reading this. Self-assembly of nanostructures is the special attraction of this nanomaterials concept, which produces huge amounts of artificial materials with different and new properties. A moth's eye has a very small  hexagonal shaped bumps on its surface and are a few hundred nanometers tall and apart due to these patterns are smaller than the wavelength of visible light (350-800nm), the moth's eye surface has a very low reflectance for the visible light so its eye can absorb more light than the other species. This help moth to have much better vision than humans in dim or dark conditions as these nanostructures absorb light very efficiently.
