  • Publication number: 20100182606
    Abstract: An apparatus and method are provided for optically measuring multiple parameters of a test sample at a regulated temperature. The test sample is held in a cuvette within a sample chamber or a fluidic channel on a fluidic chip. The temperature is sensed and modulated within a desired range. Either excitation light is directed through the test sample, and the emitted light is detected by a detector which converts the detected emission light into an output signal; or a probe light is directed to the test sample and at a detector. The output signal is transmitted to the control system which converts the output signal into output data representative of the fluorescence intensity, optical density and/or refractive index of the test sample.

  • Publication number: 20040022685
    Abstract: An identification apparatus comprising a chamber having one or more buffer fluid inlets and a plurality of sample fluid inlets, the chamber being configured such that the buffer fluid focuses the sample fluid into sample fluid streams, the sample fluid streams and buffer fluid being contained in a single laminar flow, wherein the apparatus is provided with means for directing optical excitation simultaneously at a plurality of the sample fluid streams to allow parallel fluorescence and/or scattering measurements.

  • Patent number: 6483959
    Abstract: A waveguide structure comprising a medium disposed of a sensing layer (21), a second layer of material (22) having a refractive index greater than that of the medium, and a substrate (24). The structure defines a waveguide capable of supporting an optical mode confined in a sensing layer. The medium is adapted for performing chemical or biological reactions within the medium which will result in a change of an optical property of the sensing layer of the waveguide. The thickness and refractive indexes of the layers are chosen such that an optical mode confined in the sensing layer will suffer substantially anti-resonant reflection as a consequence of the interface between the sensing layer and the second layer and the interface between the second layer and the substrate. Alternatively, the waveguide may comprise a low index sensing medium held between a superstrate and a substrate each of which has a refractive index higher than that of the medium.
