Abstract

A method for assembling many individual segmented nanorods into superstructures with control over size and shape under same environmental conditions, was investigated. A lithographically generated form is printed on a template that defines the footprint and number of rods, which can be used assembly process. Segmented nanorods, made up of gold and polypyrole (Ppy), was prepared by the porous alumina template deposition process. Photolithography applied to alumina was used to generate multiwalled DNA extraction systems and patterned arrays of rods immobilized in orientations on solid substrates. Energy-dispersive X-ray spectroscopy was used to examine the removal of silver from the process. Optical microscopy in association with atomic force microscopy (AFM) allows more definitive statements regarding the assembly mechanism.
