Abstract
A method to detect the presence and or concentration of an analyte in the environment of a spoof plasmon sensor having the steps of: providing a spoof plasmon sensor into an environment; interrogating said spoof plasmon sensor with an electromagnetic signal; collecting a modified electromagnetic signal from the spoof plasmon sensor; and analyzing the modified electromagnetic signal to detect an analyte in the environment of the sensor. A spoof plasmon sensor for detecting an analyte having a substrate with a superior surface; and a conductive material disposed on said superior surface, said conductive material defining a waveguide having a dual tapering shape, wherein said waveguide defines spoof plasmon cavities which are exposed substrate, where said substrate is configured to change in permittivity when contacted by an analyte.
