•Different chemical classes of dyes function as efficient sensors for metal ions.•Structure dependent coordination of metal ions to chromophoric receptors.•Modulation of electronic and/or physico-chemical characteristics through binding.•Material based design strategies for metal ion detection.•Highly selective and sensitive sensing of metal ions with dyes.
Recent time has witnessed unprecedented activity in the colorimetric sensing because of its low cost, practicability, selectivity as well as sensitivity. In addition to the ease in visual “naked eye” qualitative assessment of the colorimetric sensing events, the quantification can be done by resorting to spectrophotometric analysis. Additionally, a number of smart materials based on nanoparticles, carbon nanotubes, mesoporous materials, synthetic pores, conjugated polymers, etc. have been developed and used for colorimetric detection. Herein, we focus on the recent developments (last five years) in colorimetric sensing using dyes.
