Colorimetric discrimination of chrysanthemum polyphenols via tunable MOF-818 nanozyme sensor array. (PubMed, Anal Bioanal Chem) - Oct 9, 2026 - "Differential responses toward chlorogenic acid (CGA), quercetin (QR), and dicaffeoylquinic acid (DCQA) generated characteristic two-dimensional fingerprints. Combined with multivariate pattern recognition methods, including principal component analysis (PCA), linear discriminant analysis (LDA), partial least squares discriminant analysis (PLS-DA), and hierarchical cluster analysis (HCA), the sensor array enabled proof-of-concept discrimination and concentration estimation of target polyphenols. The method was successfully applied to real chrysanthemum extracts, providing a rapid, simple, cost-effective strategy for herbal quality control."
