Abstract

A simple, rapid and selective biosensor for reagent-less L-tryptophan determination has been developed. Tryptophan-2-monooxygenase was immobilized on silica gel. A Clark-type membrane 02 electrode was used as a physical transducer. A positive correlation between signal and L-tryptophan concentration was observed.
