Abstract

Gold based structures such as nanoparticles (NPs) and nanowires (NWs) have widely been used as building blocks for sensing devices in chemistry and biochemistry fields because of their unusual optical, electrical and mechanical properties. This article gives a detailed review of the new properties and fabrication methods for gold nanostructures, especially gold nanowires (GNWs), and recent developments for their use in optical and electrochemical sensing tools, such as surface enhanced Raman spectroscopy (SERS).

Keywords: gold nanoparticles (GNPs); gold nanowires (GNWs); nanoelectrodes; surface enhanced Raman spectroscopy (SERS); surface enhanced optical spectroscopy.
