colorimetric device for the detection, in an aqueous solution of interest, an enzyme activity is the hydrolytic respect of at least one polymer of interest

摘要

The present invention relates to a colorimetric device for the detection, in an aqueous solution of interest, an enzymatic activity (hydrolytic with respect to at least one polymer of interest. This device (1) comprises (i) a substrate (2) and (ii) a transparent layer of detection (3), comprising the said polymer of interest. This layer of detection (3) is designed, on the one hand, after the application of said aqueous solution of interest when the - latter is devoid of the enzymatic activity, hydrolytical class, a first thickness e, and on the other hand, due to the application of said aqueous solution of interest when the - comprises said enzymatic activity, hydrolytical class, have a second thickness of less than said first thickness e, and this first thickness e and / or this second thickness e ′ of said transparent layer of detection (3) are adapted to generate a color by an optical phenomenon of interference generated by the recombination of the reflected light beams at the interfaces (4, 5) of said layer of detection (3).
