Abstract
The invention is a SPR sensor that comprises a multi-layered plasmonic structure on a substrate for sensing. The SPR sensor has an enhanced figure of merit and lower limit of detection (system noise divided by the sensitivity) by at least two orders of magnitude than prior art SPR sensors. The plasmonic structure of the invention comprises a Nanostructured Porous Metal Layer (NPML) and at least one of: (a) buried dielectric layer under the nano-porous metal layer; (b) a nano-dimensional high index layer on top of the metal layer; and (c) a molecular layer for bio-functionalization adjacent to an analyte layer. The invention also encompasses many embodiments of measuring systems that comprise the SPR sensors of the invention with improved signal to noise ratio.
