METHOD, DEVICE AND PORTABLE METER FOR DETECTING DEGRADATION PRODUCTS OF BIOLOGICAL MOLECULES IN LAYERS OF A LAYER SYSTEM

摘要

The invention is directed to a method for the detection of degradation products of biological molecules in layers of a layer system (1) in which the degradation products are acted upon by an excitation radiation (3) and a radiation (6) of the degradation products which is induced by the excitation radiation (3) is detected and a concentration of degradation products is determined based on a comparison of the measurement values of the radiation (6) with reference data, characterized in that there is provided a layer system (1) which includes a through layer (1.1) which is transparent to the excitation radiation (3) and radiation (6) and at least one further receiver layer containing degradation products, and in that the excitation radiation (3) is directed into the receiver layer through the through layer (1.1). The invention is further directed to an apparatus and a portable measuring device (11) for detecting the degradation products.
