Abstract:
A biosensor platform for a biosensor adapted to detect one or more predetermined target analytes in a sample, the platform comprising a waveguide (202) for transporting, preferably by substantially total internal reflection, light emitted by a light source, a light source (204), such as an organic light emitting diode (OLED), for incoupling light to the waveguide, said light source being arranged on said waveguide, a binding site (214) comprising immobilized biorecognition material capable of binding to the target analytes, said 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 (206) comprising one or more microfluidic cavities for conveying the sample past said binding site so as to enable at least part of the target analytes of the sample to bind to the immobilized biorecognition material, wherein said biosensor platform is further configured to enable, when said at 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. The platform may be manufactured using a roll-to-roll technique, for example.
Abstract:
Es wird ein integriertes Testelement (110) zum Nachweis mindestens eines Analyten in einer Probe (142), insbesondere einer flüssigen Probe (142) , vorgeschlagen. Das integrierte Testelement (110) weist ein Trägerelement (112) auf, mit einer Applikationsseite (114), auf der mindestens ein organisches elektrolumineszierendes Bauelement (126) aufgebracht ist. Weiterhin ist auf der Applikationsseite (114) mindestens eine Indikatorsubstanz (136) aufgebracht, welche mindestens eine optische Eigenschaft, insbesondere eine Emissionseigenschaft (z. B. eine Fluoreszenzeigenschaft), ändert, wenn diese in Kontakt mit dem mindestens einen Analyten gerät.Weiterhin weist das integrierte Testelement (110) mindestens ein Photodetektor-Element (116) auf .
Abstract:
An optical instrument is provided for simultaneously illuminating two or more spaced-apart reaction regions with an excitation beam generated by a light source. A collimating lens can be disposed along a beam path between the light source and the reaction regions to form bundles of collimated excitation beams, wherein each bundle corresponds to a respective reaction region. Methods of analysis using the optical instrument are also pro vided.
