An amide probe as a selective Al³⁺ and Fe³⁺ sensor inside the HeLa and a549 cell lines: Pictet–Spengler reaction for the rapid detection of tryptophan amino acid

Abstract

Newly synthesized amide-based probe for the selective and specific detection of (i) Al³⁺ or Fe³⁺ ions as a cation sensor and (ii) tryptophan as an amino acid sensor.
