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.
