What Materials Are Commonly Used in Plasmonic Sensing?
The most commonly used materials in plasmonic sensing are noble metals such as gold and silver. These metals exhibit strong plasmonic resonances in the visible and near-infrared regions of the spectrum. Other materials like aluminum, copper, and certain alloys are also explored for specific applications. Additionally, advances in nanofabrication techniques have enabled the creation of complex nanostructures like nanorods, nanoshells, and nanostars, which can further enhance sensing performance.
