  • Patent number: 7867448
    Abstract: The optical sensor contains an optical waveguide (1) with a substrate (104), waveguiding material (105), a cover medium (106) and a waveguide grating structure (101-103). By means of a light source (2), light can be emitted to the waveguide grating structure (101-103) from the substrate side and/or from the cover medium side. (101-103). With means of detection (11), at least two differing light proportions (7-10) radiated from the waveguide (1) can be detected. For carrying out a measurement, the waveguide can be immovably fixed relative to the light source (2) and the means of detection (11). The waveguide grating structure (101-103) itself consists of one or several waveguide grating structure units (101-103), which if so required can be equipped with (bio-)chemo-sensitive layers. The sensor permits the generation of absolute measuring signals.

  • Patent number: 6818886
    Abstract: A method for detecting a substance or substances in a sample or in a matrix of samples combining detection methods that are, on the one hand, based on direct detection with integrated optical (bio)chemo-sensitive waveguide grating structures and, on the other hand, based on a mass-spectrometric detection effected by way of a desorption process. The method permits an increase in detection security and/or detection sensitivity.

  • Patent number: 5738825
    Abstract: A detection cell which is used as a component of an optical biosensor comprises a transparent base plate and a sample plate on the base plate. The sample plate has a matrix of wells extending through it to each to receive a sample. The base plate includes a waveguiding film and a diffraction grating means to in couple an incident light field into the waveguiding film beneath a well to generate a diffracted light field to enable detection of a change in the effective refractive index of the waveguiding film.

  • Patent number: 5071248
    Abstract: The optical sensor for the detection of specific substances and refractive index changes in gaseous, liquid, solid and porous samples is composed of integrated optical elements. It consists of a waveguiding film (1) equipped with a diffraction grating (4) and applied onto a substrate (2). For the selective detection of a specific substance contained in the sample (3) a selectively chemisorbing additional layer (5) covers the film (1) at least in the grating region. The sample (3) is applied at least in the grating region either directly onto the waveguiding film (1) or onto the selectively chemisorbing additional layer (5). Chemisorption of the substance, which is contained in the sample (3) and is to be detected, to the selectively chemisorbing additional layer (5) results in a further adlayer (6) coating the waveguiding film (1).
