indicator release system for the detection of an analyte in a food product, test tape for that system and analysis method

摘要

the present invention relates to an indicator reservoir, which comprises a porous support material and an indicator substance which is enclosed in pores of the porous support material by a releasable pore closure material, the pore closure material being bonded to the porous support material by a compound that is anchored in the porous support material, the indicator substance being released from the pores when the pore closing material binds to an analyte that is present in a liquid that wets the indicator reservoir.
