Abstract: To amplify the heat-signal generated by MIP catalyzed solvolysis of phenylacetate the reaction has been combined for the first time in a reactor with the subsequent oxidation by immobilized tyrosinase. The polymer cleaves the substrate and the released phenol is afterwards converted to o-benzoquinone by the tyrosinase. The separated and sequentially coupled reactions are characterized by the heat generated in a thermistor. The sequential substrate conversion results in a combined heat generation which results a five times higher signal than compared to the polymer alone
