A novel colorimetric and fluorescent probe for simultaneous detection of SO32-/HSO3- and HSO4- by different emission channels and its bioimaging in living cells

A simple and highly selective 1,2,4,5-tetrazine-based colorimetric probe for HSO3− ion recognition in food

“…3,4 Furthermore, endogenous sulfur dioxide derivatives are involved in many physiological processes. 5,6 For example, bisulte generated in mitochondria reduces blood pressure and aids blood vessel dilation. 7 However, recent research has shown that a high bisulte concentration in the body is not only correlated with the occurrence of allergic reactions, 8 but can also induce respiratory responses, neurological disorders, cardiovascular disease, and lung cancer.…”

Reaction-Based Ratiometric and Colorimetric Chemosensor for Bioimaging of Biosulfite in Live Cells, Zebrafish, and Food Samples

“…Therefore, it is critical to developing new analytical methods for HSO 3 – detection with good selectivity, low background interference, and high sensitivity. In contrast, analytical methods based on fluorescent probes are widely employed in the field of identification and sensing of anions, cations, and small biological molecules because of their high sensitivity, simplicity of operation, and the advantages of online analysis. − Moreover, fluorescent probing technology has great potential application value in biochemistry, medical analysis, and environmental monitoring. Therefore, the synthesis and application of fluorescent probes have received great attention, especially those for detecting anions.…”

An effective biocompatible fluorescent probe for bisulfite detection in aqueous solution, living cells, and mice

“…In contrast, hemi-cyanine has many advantages such as simple preparation, low cost, membrane permeability, organelle targeting and so on. [43][44][45] Therefore, it is highly desirable to develop a novel uorescent probe for biological samples. Many uorescent probes have previously been reported in the literature, 43,44,[46][47][48][49][50] however, improvements are required for some properties.…”

Many uorescent probes have previously been reported in the literature, 43,44,[46][47][48][49][50] however, improvements are required for some properties. Therefore, an ideal uorescent probe for in vivo bisulte detection is still needed.…”
