Abstract:
An active ion-doped waveguide-plasmon resonance (AID) WPR) sensor for analyzing a sample placed adjacent to a conductive thin film, comprisinga conductive thin film for providing surface plasmons; a dielectric medium disposed at one side of the conductive thin film; a light source for emitting an incident light beam to the conductive thin film through the dielectric medium; a dielectric thin film doped with active ions capable of fluorescing by being excited with the incident light beam, the dielectric thin film deposited at the surface of the conductive thin film opposite to the dielectric medium to act as an waveguide of surface plasmon waves and having a surface on which a sample is immobilized; and a photodetector for receiving and determining the intensity of fluorescence from the active ions.
