Patent number: 7083920Abstract: The present invention relates to methods and systems for the detection of specific sequences of nucleic acids or oligonucleotides. It relates more particularly to a conjugated enzyme based assay system utilizing reflective and/or transmissive optical bio-discs for detection of specific sequences of nucleic acids. In the assay according to the present invention, an enzyme reaction is used to detect the presence of an analyte (DNA or RNA) in a microchannel in an optical bio-disc. The analyte is immobilized by hybridization with a specific capture probe on a capture layer on the surface and the signal that is generated is localized and specific. The signal can be in the form of a pellet, a fluorescent product, and/or a colored product, and can be detected and quantified by an optical bio-disc reader utilized in conjunction with the inventions hereof. This assay is thus quantitative in nature.Type: GrantFiled: May 17, 2002Date of Patent: August 1, 2006Assignees: Nagaoka & Co.

Patent number: 7033747Abstract: Methods and apparatus for testing a sample for target molecules or chemicals. The apparatus includes a rotatable optical disc having a reaction chamber and having at least two groups of beads or micro-particles, the different group of beads having at least two different densities, sizes, shapes, and/or color, and each bead in a group having different probes attached thereto. A sample is added to the reaction chamber and the disc is rotated. The reaction chamber has a density gradient medium that causes beads of different densities to remain at different radial locations, depending on the density of the beads. The beads are then inspected by directing a beam of electromagnetic radiation onto the disc. The beam may be reflected from or transmitted through the disc. The amount, or presence, or absence of targets is determined by analyzing the signal returned from the beam. Related methods of performing assays and making the disc apparatus are provided.Type: GrantFiled: April 11, 2002Date of Patent: April 25, 2006Assignees: Nagaoka & Co., LTD, Burstein Technologies, Inc.Inventor: John Francis Gordon
