Abstract
Die Erfindung betrifft einen enzymatischen Schnelltest zum Nachweis chemischer Kampfstoffe. Das Ziel besteht darin, einen sicheren und schnellen Nachweis chemischer Kampfstoffe zu gewährleisten. Daraus leitet sich die Aufgabe ab, die Inkubationsphase gezielt zu steuern. Erfindungsgemäß werden die funktionellen Schichten (Substrat-, Enzym- und gegebenenfalls Indikatorschicht) voneinander durch eine quellfähige Sperrschicht getrennt.The invention relates to an enzymatic rapid test for the detection of chemical warfare agents. The aim is to ensure safe and rapid detection of chemical warfare agents. This leads to the task of controlling the incubation phase in a targeted manner. According to the invention, the functional layers (substrate, enzyme and optionally indicator layer) are separated from one another by a swellable barrier layer.
Description
Die Erfindung betrifft ein enzymatisches Schnellnachwoismittel zum qualitativen und semiquantitativen Nachweis chemischer Kampfstoffe (Schnelltest).The invention relates to an enzymatic Schnellnachwoismittel for qualitative and semi-quantitative detection of chemical warfare agents (rapid test).
Das Nachweisprinzip für bestimmte chemische Kampfstoffe beruht auf der durch Cholinesterase bewirkten Spaltung eines geeigneten Substrates, die durch einen pH-Indikator sichtbar gemacht wird. Bei der Hemmung des Enzyms, z. B. durch Kampfstoffe oder andere Inhibitoren, trifft die pH-Änderung durch die verzögerte Substratspaltung erheblich verspätet ein.The detection principle for certain chemical warfare agents is based on the cholinesterase-induced cleavage of a suitable substrate, which is visualized by a pH indicator. In the inhibition of the enzyme, for. As by warfare agents or other inhibitors, the change in pH due to the delayed substrate cleavage is significantly delayed.
