A chemiluminescence sensor array based on nanomaterials for discrimination of teas

In recent years, electronic tongue and nose devices have been developed that consist of an array of cross‐responsive sensors. In this study, we report a chemiluminescence (CL) sensor array based on oxidation at twelve different catalytic nanomaterial locations for the discrimination of eight teas. CL response patterns or “fingerprints” were obtained for a given compound on the sensor array and then discriminated through linear discriminant analysis. The experiments demonstrate that the sensor array had excellent differentiability and reversibility. Copyright © 2012 John Wiley & Sons, Ltd.
