A ratiometric styryl bridging triphenylamine-indolinium based fluorescent dye for detection of cyanide with a large emission shift in human breast cancer cells and test strips
ABSTRACT A new type of styryl bridging triphenyl amine-indolium conjugated dye has been developed for the colorimetric and ratiometric detection of cyanide. The detection of cyanide is confirmed by means of the fast nucleophilic attack of cyanide by the indolium group of the probe that results a speedy sensing process for cyanide with clear color and fluorescence change of the ICT process. The ratiometric fluorescence changes illustrated a linear response in the range of 0-18 μM with a low LOD value (1.7×10-7 M-1). The as-reported sensor not only function as a colorimetric sensor for “in-the-field” measurement by virtue of a “dip-stick” approach but also interact with a human breast cancer cell (MDA-MB 231) which reveals the realistic value of this probe for tracking cyanide anions in biological systems.

期刊介绍：
Supramolecular Chemistry welcomes manuscripts from the fields and sub-disciplines related to supramolecular chemistry and non-covalent interactions. From host-guest chemistry, self-assembly and systems chemistry, through materials chemistry and biochemical systems, we interpret supramolecular chemistry in the broadest possible sense. Interdisciplinary manuscripts are particularly encouraged. Manuscript types include: high priority communications; full papers; reviews, and; Methods papers, techniques tutorials highlighting procedures and technologies that are important to the field. We aim to publish papers in a timely fashion and as soon as a paper has been accepted and typeset it will be published in electronic form on the Latest articles section of the website. The two most important review criteria are that the paper presents high-quality work that fits generally into the broad spectrum of activities in the supramolecular chemistry field. Under normal circumstances, Supramolecular Chemistry does not consider manuscripts that would be more suitable in a highly specialized journal. This includes, but is not limited to, those based mostly or exclusively on topics such as solid state/X-ray structures, computational chemistry, or electrochemistry. .
