Abstract:
A biosensor platform for a biosensor adapted to detect one or more predetermined target analytes in a sample, includes a waveguide for transporting light emitted by a light source, at least one light source including an OLED, for incoupling light to the waveguide, the light source being arranged on the waveguide, a binding site including immobilized biorecognition material capable of binding to the target analytes, the binding site positioned relative to the waveguide such that evanescent field triggered by the light propagating in the waveguide extend to the binding site, a microfluidic layer including one or more microfluidic cavities for conveying the sample past the binding site to enable at least part of the target analytes of the sample to bind to the immobilized biorecognition material. The biosensor platform is configured to enable, when least part of the target analytes are bound to the immobilized biorecognition material, fluorescent markers associated with the bound target or other analytes to be excited by the evanescent field so as to emit fluorescence detectable by a detector.

Abstract:
A device, system and method for portable fluorescence detection. The portable device of the present invention features a low power light, in which a wavelength range is defined as at least one wavelength of light. The light source is preferably highly energy efficient, such that a majority of the electrical power which is consumed is then converted into transmitted light. The emitted light from the excited fluorophore is then preferably detected with any low cost and low power photodetector. Although optionally a highly sensitive optical detector may be used, preferably fluorescence is detected with any light sensing device, such as a regular photodiode or a CCD (charge-coupled device) sensor for example.

Abstract:
A substrate illumination and inspection system provides for illuminating and inspecting a substrate particularly the substrate edge. The system uses a light diffuser with a plurality of lights disposed at its exterior or interior for providing uniform diffuse illumination of a substrate. An optic and imaging system exterior of the light diffuser are used to inspect the plurality of surfaces of the substrate including specular surfaces. The optic is held at an angle from a surface normal to avoid reflective artifacts from the specular surface of the substrate. The optic can be rotated radially relative to a center point of the substrate edge to allow for focused inspection of all surfaces of the substrate edge. The plurality of lights can modulate color and intensity of light to enhance inspection of the substrate for defects.
