Chemosensor arrays are useful analytical methods in supramolecular analytical chemistry, which discriminate molecular information such as species and their concentrations based on pattern recognition. Molecular self-assembled systems can provide not only the multi-optical response patterns but also easy preparation of chemosensors. In this regard, dynamic covalent-bonds play key roles in competitive assays (i.e., indicator displacement assay (IDA)). In this review, we propose an actual approach for simple IDA-based colorimetric and fluorescent chemosensor arrays utilizing only off-the-shelf materials. With chemometrics techniques, the IDA-based chemosensor arrays successfully recognized target saccharides. Toward on-site analysis, we further applied the IDA-based chemosensor array to a paper-based analytical device. The chemosensor array on paper has achieved an accurate on-site analysis utilizing image processing without spectrophotometric instruments. The off-the-shelf material-based chemosensor arrays with pattern recognition techniques would be a novel analytical method for lab-free detections.
