Abstract
The fabrication of Au nanowire arrays by mechanical deformation using anodic porous alumina was studied. Porous alumina was pressed onto a Au surface so that Au entered the nanoholes of the porous alumina. The Au nanowire arrays were obtained by dissolving the porous alumina. For the efficient fabrication of nanowires, a nanoimprinting process was applied, which enabled the nanowires to be reproducibly obtained. The porous alumina used as the nanoimprinting mold could be reused. The nanowire arrays could be used as substrates for surface-enhanced Raman scattering measurements owing to the enhancement of the light intensity based on localized surface plasmon resonance.
