Self-assembled Emissive Probe for Efficient Sensing of Fe(III) and Cysteine in the Physiological Medium: Application in Real Water and Food Sample

A fluorescent naphthalimide-based self-assembled sensor (PAD) efficiently detects Fe( iii ) ions in the HEPES buffer, natural water samples, and food samples. The PAD⊂Fe complex can detect cysteine (Cys) exclusively from a wide range of amino acids.
