  • Patent number: 6611634
    Abstract: Improvements in a biosensor are disclosed. A biosensor includes a waveguide, at least a portion of which is substantially planar. One or more reservoirs may be formed adjacent to a chemistry-bearing surface of the waveguide. The biosensor may include a gasket to form a seal between the waveguide and side walls of the reservoir. A sample solution may be introduced into the reservoir or otherwise onto the surface of a waveguide through an input port. Waveguides of varying composition (e.g., plastic, quartz, glass, or other suitable waveguide materials) may be used in the biosensor. Also disclosed is a sled-shaped waveguide, which includes a planar portion and a lens at an end thereof and angled relative thereto for coupling light into the waveguide.
    Type: Grant
    Filed: March 11, 2002
    Date of Patent: August 26, 2003
    Assignee: University of Utah Research Foundation

  • Patent number: 6356676
    Abstract: Improvements in a biosensor of the type having reservoirs or wells for analyzing a biological liquid are disclosed. A biosensor includes a waveguide placed between a plurality of members such as plates at least one of the members being formed to define the walls of the reservoirs where the liquid is biologically analyzed. The walls of the reservoirs are made of an inert, opaque material such as a metal. Although the biosensor may include a gasket, the gasket is associated with the members and waveguide in such a way (e.g., by recessing the gasket into a channel formed into a metal plate) so that the gasket does not form any significant portion of the reservoir wall. Waveguides of varying composition (e.g., plastic, quartz or glass) may be associated with the members to form the biosensor. The metal plate of the biosensor has input and output ports for infusing, draining, or oscillating the liquid to be analyzed in the reaction reservoir.

  • Patent number: 6108463
    Abstract: Improvements in a biosensor of the type having reservoirs or wells for analyzing a biological liquid are disclosed. A biosensor (190) includes a waveguide (164) placed between a plurality of members such as plates (100, 186), at least one of the members (100) being formed to define the walls (132, 134, 136) of the reservoirs where the liquid is biologically analyzed. The walls of the reservoirs are made of an inert, opaque material such as a metal. Although the biosensor may include a gasket (162), the gasket is associated with the members and waveguide in such a way (e.g. by recessing the gasket into a channel formed into a metal plate) so that the gasket does not form any significant portion of the reservoir wall. Waveguides of varying composition (e.g. plastic, quartz or glass) may be associated with the members to form the biosensor. The metal plate of the biosensor has input and output ports for infusing, draining, or oscillating the liquid to be analyzed in the reaction reservoir.
