- Recently, metallic nanostructured materials has received intensive attention because of their potential applications for biological and chemical sensing. 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 . 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 . Metallic nanostructured materials can be utilized as a SERS platform for sensitive sensing of chemical materials .
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.
