Abstract:
A method for detecting analytes, comprising:a) providing: i) colorimetric diacetylene polymers encapsulated in porous sol-gel glass; ii) a detector; and iii) a sample suspected of comprising one or more analytes; b) exposing said colorimetric diacetylene polymers encapsulated in porous sol-gel glass to said sample such that said one or more analytes in said sample reacts with said colorimetric diacetylene polymers causing a conformational change in said colorimetric diacetylene polymers, wherein said conformational change produces a colorimetric response; c) observing said colorimetric response using said detector; and d) correlating said response to the presence or absence of said one or more analytes id said sample.
