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.
