Abstract
Recently, metallic nanostructured materials has received intensive attention because of their potential applications for biological and chemical sensing[1]. The unique optical property of the metal nanostructure is originated from localized surface plasmon resonance (LSPR), which is a collective oscillation of the conduction electrons that occurs at a specific wavelength when light impinges on metal nanostructure [1]. Surface enhanced Raman scattering (SERS) is an analytical spectroscopy technique based on the enhancement of vibrational signals of molecules adsorbed on rough metal surfaces through the LSPR [2]. Metallic nanostructured materials can be utilized as a SERS platform for sensitive sensing of chemical materials [3]. In this work, we investigated optical and electrochemical properties of metallic nanostructured materials fabricated using nanoporous alumina mask with through-holes as an evaporation mask. The optical property of Au nanodot array and Au film were measured by ultraviolet-visible spectrometer. Electrochemical property of Au nanodot array was studied by Cyclic Voltammetry.
