Abstract
The sensitivity of plasmonic particles to the immediate dielectric environment allows to monitor the dielectric constant of liquids and binding events of molecules to the gold particle surface. Here, by means of simulations and experiments, I investigate which aspect ratio (AR) of gold nanorods is ideal for plasmonic sensing by employing various measures for “ideal” behavior.
