Rapid colorimetric discrimination of cyanide ions – mechanistic insights and applications

Abstract

In this work, we have employed an intramolecular charge transfer-based DMN colorimetric probe for the rapid naked-eye detection of cyanide ions in solution as well as real water samples. The...

Nanoarchitectonics of Congo red dye to biocompatible fluorescent carbon dots for highly sensitive Fe3+ and ferritin detection

“…It was previously reported that paper-based strips were appropriate for on-site detection applications. 58,59 In this regard, we have developed a CD-adsorbed paper-based analytical device for Fe 3+ detection. Whatmann filter paper was cut into small round strips and dipped in the aqueous CD solution.…”
