✦ Synopsis

Nanostructures of various materials with different sizes and shapes have been synthesized and studied in the past few years as a result of their high impact in optoelectronic applications. In particular, one-dimensional (1D) nanostructures (nanowires, nanorods, nanotubes, etc.) show optical and electronic properties [1] that are of importance to downsize optoelectronic components to the nanometer scale. The development and integration of such 1D nanostructures relies on suitable synthetic procedures. Several methods have been designed such as template-directed synthesis, [5] solvothermal synthesis, microfabrication, metal-nanocluster-catalyzed growth, [1a] and surfactant-mediated self-assembly. In particular, template-directed synthesis offers significant advantages: ease of performance, the possibility to work under mild reaction conditions, and above all the control over unique, well-defined morphologies of the resulting nanostructures. Various kinds of templates, such as porous alumina, molecular sieves, proteins, [5a] DNA, [5b] viruses, [5c] and selfassembled monolayers, have been reported to guide the nanowires, 1 % rhodamine-labeled lipids (TRITC-DHPE, Molecular Probes) was added.
