  • Molecular detection apparatus and method
    Patent number: 6117630
    Abstract: An apparatus comprises a disk-shaped support member (20) supporting a first sample-processing device (28) and a second sample-processing device (30). The first sample-processing device (28) has an elongate portion oriented along a first radial axis (32) of the support member (20). The second sample-processing device (30) has an elongate portion oriented along a second radial axis (34) transverse to the first radial axis (32). A sample-processing device can comprise a plurality of conduits (150) interconnected in a tree topology to couple an inlet (152) with a plurality of outlets (154). The inlet (152) is located at a root vertex and each of the outlets (154) is located at a corresponding leaf vertex of the tree topology. Each of a plurality of molecular detection chambers (156) is coupled to a respective one of the outlets (154). A method of using the apparatus is disclosed.
    Type: Grant
    Filed: September 27, 1999
    Date of Patent: September 12, 2000
    Assignee: Motorola, Inc.
