“…For example, Zhang et al [30] used magnetron sputtering into anodic alumina membranes to prepare 40-70 nm-diameter Ag nanowires. Kim et al [31] used electroless deposition into anodic alumina to prepare silver nanowires with diameters between 20 and 200 nm; Sun et al [32] and Sauer et al [33] have reported electrodeposition of 100 nm-and 30-70 nm-diameter silver nanowires, respectively, into anodic alumina templates from aqueous solution.…”

Cyclic voltammetry of silver coordination complexes in acetonitrile and in a single-phase supercritical carbon dioxide/acetonitrile (scCO2/CH3CN) system is reported. Five silver precursors are investigated: (1,5-cyclooctadiene)(hexafluoroacetylacetonato) silver(I) [Ag(hfac)(COD)], (hexafluoroacetylacetonato)(triphenylphosphine) silver(I) [Ag(hfac)(PPh3)], (perfluorooctanoato)bis(triphenylphosphine) silver(I) [Ag(CF3(CF2)6CO2)(PPh3)2], tetrakis(triphenylphosphine) silver(I) tetrafluoroborate [Ag(PPh3)4][BF4] and tetrakis(acetonitrile) silver(I) tetrafluoroborate [Ag(CH3CN)4][BF4]. Of these, [Ag(CH3CN)4][BF4] is found to be the most suitable for electrodeposition of silver from scCO2/CH3CN.

“…In this work, we show that chemically enhanced AAO porous structures can be a promising material candidate to produce large size and cost-effective novel nanowire structures with unique surface topography, in comparison to existing techniques, e.g., electron beam lithography (EBL), focused ion beam (FIB), laser writing, etc. The fabrication of AAO-based metal/semiconductor nanowires has been possible using electrodeposition, electroless deposition, pore widening of AAO pores, and branching of AAO pores via changing the voltage during the anodization. ,− We performed a simple wet etching for pore widening, and different template drying processes were added after the production of porous AAO to fabricate high-performance multifunctional substrates. We report the fabrication of AAO nanowire structures with novel surface topography for spectral selective plasmonic absorber with tunable bandwidth and high efficiency (>90%).…”

In this study, a plasmonically active substrate is developed with the aim of controlling the perfect absorption and manipulating its optical properties for application in SERS (in NIR regime) and colorimetry. Based on modified fabrication method of anodized aluminum oxide (AAO), the cost-effective selfaggregation technique is presented to fabricate unique topography of bone-fire-like funnel-shaped collapsed and vertically aligned nanowire structures. The length of the nanowire and the modification of surface topography induced by capillary force inside the nanowire are set to structural parameters, and the effect of their changes is closely studied. After deposition of 40 nm gold (Au) film on numerous AAO nanowire structures with different wire lengths and unique topography, the localized surface plasmon resonance excitation is generated, and also its application on reflection and SERS spectra have been shown quantitatively. The length of the wire and surface topography modification are identified as suitable parameters to tune the reflection/absorption (from <40 to >90%) as well as colorimetric effect. Finally, an optimized wire length of Au-coated AAO substrate in SERS sensing application with 3.92 × 10 5 order of enhancement of rhodamine 6G (R6G) Raman signal is demonstrated.

Self-assembly offers unique possibilities for fabricating nanostructures, with different morphologies and properties, typically from vapor or liquid phase precursors. Molecular units, nanoparticles, biological molecules and other discrete elements can spontaneously organise or form via interactions at the nanoscale. Currently, nanoscale self-assembly finds applications in a wide variety of areas including carbon nanomaterials and semiconductor nanowires, semiconductor heterojunctions and superlattices, the deposition of quantum dots, drug delivery, such as mRNA-based vaccines, and modern integrated circuits and nanoelectronics, to name a few. Recent advancements in drug delivery, silicon nanoelectronics, lasers and nanotechnology in general, owing to nanoscale self-assembly, coupled with its versatility, simplicity and scalability, have highlighted its importance and potential for fabricating more complex nanostructures with advanced functionalities in the future. This review aims to provide readers with concise information about the basic concepts of nanoscale self-assembly, its applications to date, and future outlook. First, an overview of various self-assembly techniques such as vapour deposition, colloidal growth, molecular self-assembly and directed self-assembly/hybrid approaches are discussed. Applications in diverse fields involving specific examples of nanoscale self-assembly then highlight the state of the art and finally, the future outlook for nanoscale self-assembly and potential for more complex nanomaterial assemblies in the future as technological functionality increases.
