摘要
This invention concerns a colorimetric device for detecting, in an aqueous solution of interest, a hydrolytic enzymatic activity with regard to at least one polymer of interest. This device (1) includes (i) a substrate (2) and (ii) a transparent detection layer (3), including the said polymer of interest. This detection layer (3) is adapted so that, on the one hand, after application of the said aqueous solution of interest, when it is deprived of said hydrolytic enzymatic activity, it preserves the said first thickness e, and on the other, after the application of the said aqueous solution of interest, when it includes the said hydrolytic enzymatic activity, it has a second thickness e′, thinner than the said first thickness e, and the said first thickness e and/or the said second thickness e′ of the said detection layer (3) are adapted to generate a color by an optical interference phenomenon caused by the recombining of the light beams reflected at the interfaces (4, 5) of the said detection layer (5).
