Claims25
A device for detecting an organophosphate (OP) and carbamate (C) “OP/C” compound comprising:
- a top piece, a middle piece, and a bottom piece,
- wherein said top piece comprises a first carrier material comprising an immobilized OP/C Detecting Enzyme;
- wherein said middle piece comprises a second carrier material and an ampoule comprising a buffer;
- and
- wherein a first substrate, a second enzyme, a second substrate, and a pH Sensitive Dye are localized in the top piece, the middle piece, or the ampoule;
- and
- wherein when the middle piece is turned relative to either the top piece or the bottom piece, the ampoule is capable of being cracked to release the buffer to contact the first carrier material and the second carrier material causing:
- (i) an enzymatic conversion of the first substrate by the immobilized OP-Detecting Enzyme to produce an acidic reaction product;
- and
- (ii) an enzymatic conversion of the second substrate by the second enzyme to produce a basic reaction product.
