    摘要: A biosensor and a method of detecting one or more analytes is disclosed. The biosensor comprising a waveguide for receiving and propagating an optical radiation along the length of the waveguide as a long range surface plasmon-polariton (LRSPP) wave with its transverse electric field substantially perpendicular to the width of the waveguide. The waveguide comprising an input region for receiving the optical radiation at one end; an output region at an opposed end for emitting the propagated optical radiation away from the waveguide and towards a detector; and a sensing region between the input and output region; a dielectric cladding surrounding the waveguide; and at least one fluidic channel formed in the dielectric cladding for moving a fluid towards and away from the sensing region. In some embodiments, the biosensor and methods for analyte detection feature one or more of the following : high detection sensitivity and specificity, scalability and multiplex capacity, ability to simultaneously analyze a plurality of different analytes, and ability to detect or measure multiple individual binding events in real-time.

    摘要: This patent document discloses techniques, systems, and devices for detecting a target substance using optical nonlinear wave mixing for enhanced detection sensitivity and accuracy. In one aspect, a method for measuring α-synuclein in a body fluid of a patient with high detection sensitivity and accuracy and providing early stage Parkinson's disease detection is provided. The method may comprise: supplying to a capillary analyte cell a fluidic sample that includes a body fluid of a patient containing α-synuclein, wherein the capillary analyte cell is located in a nonlinear optical four-wave mixing device; directing laser light from the nonlinear optical four-wave mixing device into the capillary analyte cell to cause nonlinear optical four- wave mixing in the fluidic sample to generate a four-wave mixing signal that contains information on the α-synuclein in the fluidic sample; and processing the four-wave mixing signal to extract information on the α-synuclein in the fluidic sample.
