Fluorimetric detection and discrimination of α-amino acids based on tricyclic basic dyes and cucurbiturils supramolecular assembly

A sensor array made by combining four fluorescent tricyclic basic dyes with cucurbiturils is able to identify and discriminate 18 alpha-amino acids up to 10(-4) M without the need of enzyme activation. (c) 2011 Elsevier Ltd. All rights reserved.
