  • METHOD AND DEVICE FOR DETECTING PHOTOSYNTHETIC INHIBITION
    Publication number: 20080169431
    Abstract: This invention relates to systems and test strips for detecting the photosynthesis-inhibitory activity of substances by providing cells or cell parts with an intact photosystem, introducing the cells or cell parts into a planar layer, applying the test substance to the planar layer or into the planar layer, excitation of the luminescence of the cells or cell parts in the planar layer by an excitation light source, measuring the luminescence of the cells or the cell parts in the planar layer by means of a detector, and associating the detector signal with the degree of photosynthesis inhibition.
    Type: Application
    Filed: December 21, 2007
    Publication date: July 17, 2008
    Applicant: BAYER INNOVATION GMBH
    Inventors: Wolfgang Kreiss, Mark Wilhelm Drewes, Gunther Eberz, Norbert Caspers
