In many cases, metal silicides may very well be the catalysts. For example, FeSi2 is being considered to be the catalyst in Fe-assisted nanowire synthesis. This is similar to the silicon mono-oxide case, although it is much easier to understand the mechanisms in the FeSi2 case. It is also possible that during the catalytic processes that silicon diffuses relatively freely through the metal catalyst and consequently, the observed silicides at the end of reaction may be different from those during the catalytic reaction. No direct evidence is available to show whether metal or metal silicide nanoparticles are the tme catalyst.

Fig. 13.6 In-situ nanowire synthesis The working electrode and counter electrode are contacted by probe tips. A probe tip is also used as a pseudo reference electrode, submerged in the solution containing the analyte. The nanowire (red) is growing in the direction of the arrow, from the working electrode to the counter electrode, confined to a predetermined path by the photoresist. The inset shows an SEM micrograph of a polypyrrole nanowire fabricated by in-situ synthesis...

Long nanochannels can be used as single molecule sensors in a similar way as nanopores, as has been demonstrated in several recent studies. In addition to the application as single molecule sensors, long nanochannels and their arrays can be used as filters for molecule separation, membranes for electroosmotic pumping, templates for nanowire synthesis, electrodes for supercapacitors, and proton exchange membranes in fuel cells. Novel and complex transport phenomena can occur in nanochannels, leading to improved performance or new functions for devices made of nanochannels.

Since the first report of nanowire synthesis by Possin in 1970, many nanowires have been made, but the synthesis of nanotubes requires a delicate control of experimental parameters, such as concentration and reaction times. Only in the...
