Aligned polymer nanowire structures

Aligned polymer nanowire structures have been developed using an electrochemical deposition technique to form aligned PAn arrays on smooth and textured electrode substrates without the need for a porous templating structure.248 249 Ori-... 

In addition to synthetic polymer stmctures, highly aligned DNA nanowires (i.e., spokes) were successfully created by confining aqueous DNA solutions to a curve-on-flat geometry (i.e., sphere-on-flat or cylinder-on-flat) during evaporation (Fig. 3.13) [140], Unlike coffee-ring structures (or stripes), DNA nanowires formed perpendicular to the contact line. The extremities of DNA were able to anchor to the... 

Electrodeposition into templates. A most often used approach to create aligned nanostructures (such as nanowires, -tubes and similar, perpendicular to the electrode) is deposition into a nanoporous template. Such templates may be - as illustrated in Fig. 1 - porous alumina, self-assembled polystyrene beads, ion track-etch channels. Both cathodic and anodic electrodeposition of structures can be achieved, such as metal oxides, sulfides, or tellurides, as well as polymers. " °°...
