A very recent paper details the biomolecular functionalization of a polypyrrole nanowire. ZnSe/CdSe quantum dots were functionalized with avidin and these quantum dots were incorporated into a polypyrrole nanowire during its electrochemical formation between two electrodes 100 nm apart [32], Biotin with a DNA strand attached was shown to modulate the conductivity of the avidin nanowire, but not an unfunctionalized polypyrrole nanowire fabricated similarly. Presumably, the DNA-biotin-avidin complex would also be sensitive to changes in the hybridization state of the DNA. 

A number of other porous materials may be used as the host matrices for nanowire fabrication. A mesoporous molecular sieve termed MCM-41 (Beck et al., 1992) possesses hexagonally packed pores with very small... 

Electrochemical deposition has attracted increasing attention as a technique for nanowire fabrication. Traditionally, electrochemistry has been used to grow thin films on conducting surfaces. Because electrochemical... 

In contrast to nanowires synthesized by the pressure injection method, nanowires derived electrochemically are typically polycrystalline with no preferred crystal orientation. However, some exceptions occur. For example, polycrystalline CdS nanowires fabricated by ac electrodeposition in anodic alumina were shown to have a preferred wire growth orientation along the c axis (Routkevitch et al., 1996). Recently, Xu et al. (2000a, 2000b) prepared...

Among other reports, the DNA-templated Cu nanowire fabrication by electroless metallization100 or biotemplate synthesis of 3-nm nickel and cobalt nanowires, which may find reality in biomedical applications,101 should be mentioned. 

Interest in the synthesis and processing of mesoporous silica materials has grown extensively since their discovery in 1992, and the exciting potential that these films hold in low-k dielectrics, sensors, nanowire fabrication, catalysis, membrane separations, and many other applications will continue to fuel academic and industrial interest in these films. While there are many new synthesis routes for processing mesoporous silica thin films, spin coating and dip coating remain the most facile methods available. These methods deliver high quality reproducible films that can be used for any of the variety of applications. 

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...

Figure 10.6 Procedure for polymer nanowire fabrication. An aqueous PEDOTtPSS solution was spin-coated on a substrate patterned with a 1.3 ym period grating, then coated with a thin Si02 layer and a PDMS homopolymer brush. A PS-PDMS block-copolymer thin film was then spin-coated and solvent-annealed. The self-assembled block-copolymer patterns were transferred into the underlying PEDOT-.PSS film through a series of reactive ion etching steps employing CF4 and O2 plasmas.
