Finally, metal nanostructures were examined as new materials for ethylene epoxidation, which is in the form of silver nanoparticles, nanotubes, nanowires, nanocubes, and a silver-containing polyoxometallate (73,74). With the current popularity of nanotechnology in new materials, more of these systems are bound to be seen in the future. 

The field of nanolithography is intimately connected with nanomanipulation. In nanomanipulation generally a preformed nanoparticle, nanotube or a nanowire is manipulated to place it at a predetermined site. The most widely used tool for nanomanipulation is the cantilever of the AFM that provides a robotic arm to place the nano-objects in predetermined sites. A nanoparticle weakly adsorbed on a substrate can be moved by an AFM tip when it works in contact mode. This is not wanted but if the particle is selected and then moved by the AFM then it becomes a useful tool. The AFM-based manipulation turns the unwanted aspect to an advantage. For instance if one wants to place a nanowire between two electrodes an AFM cantilever can be used to image the wire and push it between the two electrodes. The advantage of the cantilever is that a predetermined force can be applied and also the same instrument can image it. The basic idea behind SPM-based nanomanipulation is shown in Figure 21.17.

Nanomaterials represent today s cutting edge in the development of novel advanced materials, which promise tailor-made functionality for unique applications in all important industrial sectors. Nanomaterials can be clusters of atoms, grains 100 nm in size, fibers that are less than 100 nm in diameter, films that are less than 100 nm in thickness, nanoholes, and composites that are a combination of these. In other words, it implies that the microstructures (crystallites, crystal boundaries) are nanoscale [1]. Nanomaterials include atom clusters, nanoparticles, nanotubes, nanorods, nanowires, nanobelts, nanofilms, compact nanostructured bulk materials, and nanoporous materials [2]. Materials in nanosize range exhibit... 

Nanomaterials can be subdivided as nanoparticles, nanotubes, nanorods, quantum dots, etc. according to their size and properties.
