Plasmonic nanostructures have been explored for a wide variety of applications due to their ability to control light at the nanoscale. However, plasmonic nanoantennas based on conventional metals are difficult to tune after fabrication due to fixed material properties. By contrast, the properties of organic conducting polymers can be tuned via their redox state, and they can be optically metallic in their oxidized state [1]. Here, I will present our recent work demonstrating that nanodisks of a highly conducting polymer can sustain plasmonic resonances in the near-infrared and act as switchable optical nanoantennas [2].
