Pattern recognition of amino acids based on highly fluorescent SDS modified pyridyl thiazole derivative

•Pyridyl thiazole fluorophore for the selective optical sensing of aspartic and glutamic acid.•Modification of fluorophore with SDS assemblies for the discriminative sensing of acidic and basic amino acids.•A turn on fluorescence response for acidic amino acids and a turn off sensing for basic amino acids.•Principal component analysis for the classification and clustering of acidic, basic and neutral amino acids.
