Method and device for the detection of phenylalanine in biological samples

Abstract

The invention relates to a method for the detection of phenylalanine in biological samples and to the corresponding reading device. More specifically, the invention refers to an enzymatic detection method and the detection device comprises a disposable sensor within which both the enzymatic recognition reaction and the colorimetric transduction of phenylalanine through the formation of metal nanostructures with characteristic optical absorption properties take place.
