Indicator release system for the detection of an analyte in a foodstuff, test strip therefor, and analysis method

摘要

An indicator reservoir, comprising a porous support material and an indicator substance which is enclosed in pores of the porous support material by a releasable pore-closing material, the pore closing material being bound to the porous support material by a compound that is anchored to the porous support material, the indicator substance being released from the pores when the pore-closing material binds an analyte being present in a liquid that wets the indicator reservoir.
