 | This work sought to develop chemical components and self-assembly techniques for molecular electronic circuits. Specific objectives were to use membrane replication methods to make segmented metal and semiconductor rod colloids, and to develop techniques for assembling them into cross-point arrays for functional circuits. The major accomplishments were demonstration of nanowire synthesis down to diameters of 12 nm with aspect ratios exceeding 100, development of an electrofluidic technique for aligning and ... |

| The functionalization of an array of eight, closely-spaced (1.2 microns) Pt or Au microelectrodes each 50 microns long, 2 microns wide, and 0.1 microns thick with redox active WO3 and polyaniline and the electrochemical characterization of the WO3/polyaniline junction is reported. Chips consisting of microfabricated WO3 covering three of the available eight microelectrodes have been analyzed by Auger electron spectroscopy. The remaining five microelectrodes are available for further derivatization with ... |

 | Properties of arrays of closely spaced (1.2 micron) Au or Pt microelectrodes (approx. 2 micron wide x 50 micron long x 0.1 micron high) coated with cathodically grown films of Ni(OH)2 are reported. Electrical connection of microelectrodes by Ni(OH)2 was verified by cyclic voltammetry. The ratio of anodic charge to cathodic charge in cyclic voltammograms for the Ni(OH) 2 = NiO(OH) interconversion exceeds one. However, it is shown that excess ... |

| Electrochemical properties of an array of closely spaced (1.2 micron) Au or Pt microelectrodes (approx. 2 micron wide x approx. 50 micron long x 0.1 micron high) coated by a 0.15 micron thick layer of polycrystalline W03 are reported. The W03 is deposited on the electrodes by rf sputtering of a W03 target. The cyclic voltammetry of these microelectrodes indicates that W03 connects individual microelectrodes, since the voltammogram of a ... |

| Microelectrode arrays consisting of two or eight closely spaced (approx. 1 micrometer) Au or Pt microelectrodes (approx. 2 micrometers wide x approx. 50 micrometers long x 0.1 micrometer high) can be modified with a variety of redox active materials in a way that leads to microelectrochemical devices that may be useful as sensors. In general, a pair of microelectrodes connected by a redox active material represents a device, because the ... |
