    Abstract: Techniques are described for the detection of multiple target species in real-time PCR (polymerase chain reaction). For example, a system comprises a data acquisition device and a detection device coupled to the data acquisition device. The detection device includes a rotating disk having a plurality of process chambers having a plurality of species that emit fluorescent light at different wavelengths. The device further includes a plurality of removable optical modules that are optically configured to excite the species and capture fluorescent light emitted by the species at different wavelengths. A fiber optic bundle coupled to the plurality of removable optical modules conveys the fluorescent light from the optical modules to a single detector. The device further includes a heating element for heating one or more process chambers on the disk. In addition, the device may control the flow of fluid in the disk by locating and selectively opening valves separating chambers by heating the valves with a laser.

    Abstract: This specification discloses various improvements in the field of SPR sensing systems. One improvement relates to a portable SPR sensing system, e.g., a system contained within a suitcase that can be hand-carried to a monitoring site. Another improvement relates to a portable, cartridge-based SPR sensing system. In this system, selected portions of the system's electrical and fluidics systems are allocated between a base unit and a removable/disposable cartridge. Other improvements relate to methods or protocols for operating an SPR sensing system. Such methods provide for the elimination of false positives and increased sensitivity, e.g., by using secondary antibodies with specificity for different target epitopes and by sensor element redundancy. In addition, protocols are provided for the detection of small molecules. Such protocols may employ a competition type assay where the presence of the analyte inhibits the binding of antibodies to surface immobilized analyte, or a displacement assay, where antibodies bound to the analyte on the sensor surface are displaced by free analyte.

    Abstract: Optical interrogation systems and methods are described herein that are capable of measuring the angles (or changes in the angles) at which light reflects, transmits, scatters, or is emitted from an array of sensors or specimens that are distributed over a large area 2-dimensional array. In one embodiment of the present invention, the optical interrogation system has a far-field diffraction measurement configuration so it can simultaneously receive the light from sensors in all or a sub-section of a sensor array at a detector. In another embodiment of the present invention, the optical interrogation system incorporates an anamorphic optical receive system that enables parallel detection of angular responses from the sensors in the 2D array. In yet another embodiment of the present invention, the optical interrogation system incorporates an angular measurement system which measures the change in angular tilt of the sensor plane when the sensor array is moved or removed and then replaced in the measurement system. Several other embodiments of optical interrogation systems and methods are also described herein. A significant advantage of the present invention is that the system has no critical moving or scanning parts, which are frequently the source of measurement sensitivity limitations.
