Abstract Differential sensing, inspired by the olfactory systems in mammals, utilizes cross‐reactivity of multiple sensor units toward analytes to generate a distinctive fingerprint for each analyte. Widely acknowledged as robust analytical technique, differential sensing has entered flourishing era with advancement machine learning. Nevertheless, developing and optimizing signal transduction remain significant tasks left chemists. Macrocyclic receptors serve promising materials constructing arrays enhanced cross‐reactivity, facilitated their ease synthesis derivatization, inherent broad‐spectrum encapsulation capability, compatibility responsive approaches. Herein, we present concise overview fundamental processes involved array, encompassing array construction, transduction, data acquisition analysis, an emphasis on unique advantages provided macrocyclic former two aspects. Then, fascinating application scenarios where shine that rely various ingenious strategies. Finally, discuss several issues potential improvement future directions receptor‐based offering forward‐looking perspective.

Lonicerae japonicae flos (LJF) and (LF) are traditional Chinese herbs that commonly used widely known for their medicinal properties edibility. Although they may have a similar appearance vary slightly in chemical composition, effectiveness as medicine use clinical settings significantly, making them unsuitable substitution. In this study, novel 2 × 3 six-channel fluorescent sensor array is proposed uses machine learning algorithms combination with the indicator displacement assay (IDA) method to quickly identify LJF LF. This comprises two coumarin-based indicators (ES MS) three diboronic acid-substituted 4,4′-bipyridinium cation quenchers (Q1–Q3), forming six dynamic complexes (C1–C6). When these react ortho-dihydroxy groups of phenolic acid compounds LF, release different indicators, which turn causes distinct fluorescence recovery. By optimizing eight algorithms, model achieved 100% 98.21% accuracy rates testing set cross-validation predictions, respectively, distinguishing between LF using Linear Discriminant Analysis (LDA). The integration shows great potential analyzing detecting foods pharmaceuticals contain polyphenols.
