Unveiling of a smartphone-mediated ratiometric chemosensor towards the nanomolar level detection of lethal CN⁻: combined experimental and theoretical validation with the proposition of a molecular logic circuitry

Abstract

A ratiometric chemosensor (DNMH) is unveiled herein, demonstrating selective chromogenic response towards CN−, with a LOD of 278 nM. Consequently, molecular logic circuitry and a smartphone-based colorimetric sensory prototype has been explored.

Recent endeavours in the development of organo chromo-fluorogenic probes towards the targeted detection of the toxic industrial pollutants Cu2+ and CN−: recognition to implementation in sensory device

“…Banerjee et al 113 unveiled a promising and hitherto unexplored naphthalene-functionalized chemoreceptor, probe 80 , which demonstrated brisk discernible chromogenic changes from yellow to red in the presence of CN − in a near-perfect aqueous solvent. Sophisticated analytical investigations further manifested the underlying recognition mechanism.…”
