“…Due to different thermal expansion coeffi cients between alumina and aluminum substrate, pore cracking was claimed to occur during heating and cooling [15], which will certainly affect the form of carbon tubes grown in the pores. Extensive TEM observations show that carbon tubes grown in PAAF with aluminum substrate have the same round feature as that in PAAF without aluminum substrate.…”

“…The deposited material has to be electrically conductive to sustain the growth after initial oxidation/reduction of the target species on the electrode. Although this issue prohibits fabrication of insulators by this method, a large variety of materials such as metals (Zeng, 2000;Davydov, 1999;Iwasaki, 1999;Ferre, 1997;Li, 2001;Haddon, 2002), alloys (Saedi, 2005, semiconductors (Ferain, 1993), superconductors (Sloan, 2002), and conducting polymers (Wang, 1998) can be deposited electrochemically. Electrochemical deposition, in general, is performed by application of an electrical field to a solution containing the ions of a target species.…”

There is a critical need for more accurate, highly sensitive and specific assay for disease diagnosis and management. A novel, multiplexed, single sensor using rapid and label free electrochemical impedance spectroscopy tuning method has been developed. The key challenges while monitoring multiple targets is frequency overlap. Here we describe the methods to circumvent the overlap, tune by use of nanoparticle (NP) and discuss the various fabrication and characterization methods to develop this technique. First sensors were fabricated using printed circuit board (PCB) technology and nickel and gold layers were electrodeposited onto the PCB sensors. An off-chip conjugation of gold NP's to molecular recognition elements (with verification technique) is described as well. A standard covalent immobilization of the molecular recognition elements is also discussed with quality control techniques. Finally use and verification of sensitivity and specificity is also presented. By use of gold NP's of various sizes, we have demonstrated the possibility and shown little loss of sensitivity and specificity in the molecular recognition of inflammatory markers as "model" targets for our tuning system. By selection of other sized NP's or NP's of various materials, the tuning effect can be further exploited. The novel platform technology developed could be utilized in critical care, clinical management and at home health and disease management.

“…[6][7][8][9][10] AAO membrane is prepared from aluminum metal by electrochemical anodization in an electrolytic cell. While the technology of AAO and its application has a long history, 11 basic research on self-organization of nanostructures via AAO templates began much more recently, with self-organizing and prepattern guided anodization techniques.…”

:Highly ordered and perforated anodic aluminum oxide membranes were prepared by anodic oxidation and subsequent removal of the barrier layer. By using these homemade anodic aluminum oxide membranes as templates, metal selenide nanowires and nanotubes were synthesized. The structure and composition of these one-dimensional nanomaterials were studied by field emission scanning electron microscopy as well as transmission electron microscopy and energy dispersive Xray spectroscopy. The growth process of metal selenide inside anodic aluminum oxide channel was traced by investigating the series of samples using scanning electron microscopy after reacting for different times. Straight and dense copper selenide and silver selenide nanowires with a uniform diameter were successfully prepared. In case of nickel selenide, nanotubes were preferentially formed. Phase and crystallinity of the nanostructured materials were also investigated.
