The synergistic combination of layer-by-layer (LbL) assembly and nanoporous membrane templating has greatly facilitated the creation of complex and functional nanotubular structures. The approach takes advantage of both the new properties conferred by assembling diverse LbL building blocks and the tight dimensional control offered by nanotemplating to enable new functionalities that arise from the highly anisotropic “one-dimensional” LbL-nanotube format. In this review, we aim to convey the key developments and provide a current snap-shot of such templated LbL nanoarchitectures. We survey recent developments that have enabled the assembly of polymers, biomolecules and inorganic nanoparticles “à la carte”, via electrostatic, covalent and specific (bio)recognition interactions. We also discuss the emerging mechanistic understanding of the LbL assembly process within the nanopore environment. Finally, we present a diverse range of LbL nanotube “devices” to illustrate the versatility of the nanotemplated LbL toolbox for generating functional soft nanotechnology.

In the present paper, the use of high aspect ratio metallic nanowires (NWs) as functional interconnects between three-dimensionally stacked chips is proposed. First practical preparation steps, as there are the preparation of templates and the deposition of Ag-NWs, are presented. Later on, the applicational technology for vertically aligned NWs is proposed as their embedment into a polymer matrix resulting in an anisotropically conductive composite film. This is discussed in both technological and functional aspects.

“…It is reasonable to assume that the reactivity of AAO, and therefore the way in which single-source-precursors infiltrated into its pores react, can be adjusted by proper selection of the reaction conditions. Nevertheless, only little effort has been devoted to inducing precursors to react with the hard template in a specific way depending on the reaction conditions [32,33,[42][43][44]. For example, Wang et al had AAO react with elemental zinc prepared in situ by H 2 -reduction of ZnS and obtained ZnAl 2 O 4 and ZnO nanostructures [43,44].…”

Shape-defining hard templates containing arrays of aligned cylindrical nanopores have been exploited as a powerful tool in the synthesis of tubular; rod-like, and core shell-type one-dimensional (ID) nanostructures consisting of inorganic materials. Gaining control over the crystallinity, the crystal orientation, and the internal morphology of the products is a challenging task and obviously turns out to be crucial for adjusting the properties of the nanostructures. Template-controlled thermolysis of single-source-precursors inside nanoporous hard templates is a versatile route toward single-crystalline nanorods, but also polycrystalline and complex nanostructures can be produced. By alterations of the 'single-source-precursors and reaction conditions and by exploiting the hard templates as reactants, several target materials, including compound semiconductors, metals, and spinel-type materials of varying crystallinity and morphology can be obtained. Moreover, core-shell nanowires have been accessible in this way. synthesized inside macroporous silicon or mesoporous alumina templates exhibit large aspect ratios and high uniformity in size and shape. Therefore the template-assisted-thermolysis of single-source-precursors represents a well-defined platform toward the straightforward synthesis and characterization of ID inorganic nanostructures
