Abstract

A flow-through optosensor for tryptophan is described. The sensor is developed in conjunction with a flow-injection analysis system and uses immobilized β-cyclodextrin as the sensing agent. The detection limit for tryptophan was 4ng ml−1. The RSD for determination of 1 μg ml−1 of tryptophan was 2.8%.
