A smart switchable module for the detection of multiple ions via turn-on dual-optical readout and their cell imaging studies

Abstract

A module switchable as a function of multi-stimuli response has been designed. The module displays sequential logic gate-based detection of multiple ions (Fe³⁺, Hg²⁺, CN⁻ and S²⁻) at ppm levels via a “turn on” signature which potentially meets real-world-challenges through a simple synthetic route, a fast response, water based-activity, naked-eye visualization, regenerative-action, high selectivity and multiple readout for precise analysis. Living cell imaging of Fe³⁺ and Hg²⁺ has also been carried out in HeLa cell lines.
