Abstract:
The invention relates to a method and at least one arrangement for detecting biological and/or chemical substances. A light beam or a light bundle generated by a pumped light energy source with an excitation wavelength ?? is directed onto a carrier substrate, on which an optical function structure in the form of an organic luminous means is situated, on which in turn the substance(s) to be detected is/are deposited in a suitable form, such that the difference wavelength ??? or XR produced as a result of absorption and changed diffraction optical properties is captured using a suitable receiver, and an evaluation unit that is coupled thereto is used to detect the substances on the basis of a data comparison system. The organic phosphor is preferably at least one organic distributed feedback laser (DFB laser). The method and a special arrangement can also be used to detect a specific substance using individual laser pixels (2P).
