Abstract
A surface plasmon resonance sensor including: a substrate-mode metal film coated waveguide cartridge including: a planar waveguide including a plurality of reflector surfaces within the planar waveguide; and a metal film deposited directly on the planar waveguide, the metal film and the planar waveguide defining a plasmon resonance interface directly on the planar waveguide; a sample flow cell adjacent the substrate-mode metal film coated waveguide cartridge; a transverse magnetic polarized light source optically connected to the planar waveguide; a cylindrical diverging lens optically connected to the planar waveguide; and a detector array comprising a plurality of photodetectors optically connected to the cylindrical diverging lens. Methods of using the surface plasmon resonance sensor are also disclosed.
