  • Patent number: 8072585
    Abstract: A multi-modal data acquisition system for detecting target material on a biological reaction surface, the system comprising a radiation source for generating an incoming beam that impinges on the biological reaction surface at an oblique incidence angle and produces a reflected beam, an interferometric detector for detecting an interferometric signal from the illuminated surface, the reflected beam being directed to the interferometric detector, a fluorescence detector for detecting a fluorescence signal from the illuminated surface; the fluorescence detector being positioned to substantially minimize the incidence of the reflected beam; and a processing system for receiving the interferometric and fluorescence signals and determining the presence or absence of target material on the biological reaction surface. A reaction surface conditioned for the simultaneous collection of fluorescence, interferometric and other signals.

  • Publication number: 20080230605
    Abstract: A process for maintaining data integrity of a sample. The process includes scanning a substrate barcode, scanning a sample barcode, placing the sample into a rack at a position that is identified, depositing the sample onto the substrate at a trackable well location, re-scanning the substrate barcode, analyzing the substrate to collect data representative of the deposited sample, and displaying the representative data. The substrate barcode and the sample barcode can be configured to relay information to a software program, which is also configured to identify and store information related to the trackable well location where the sample is placed on the substrate. The substrate barcode can also be configured to indicate a characteristic of the deposited sample and relay it to the software program.
