Abstract
System and methods for detecting analytes are provided. The system includes a plasmonic interferometer with a first surface having a first and second scattering element and an aperture disposed between the first scattering element and the second scattering element. A first distance between the aperture and the first scattering element and a second distance between the aperture and the second scattering element are selected to provide interference of light at the slit. The system also includes a light source for illuminating the first surface of the plasmonic interferometer, a detector positioned for detecting light transmitted through the aperture, and a sample holder for disposing a sample to be analyzed onto the first surface of the plasmonic interferometer.
