Novel fluorescent chemosensor for Ag+ based on coumarin fluorophore

Synthesis and Structural Characterization of Azine Based Chemosensors for Ag+ Ion Detection and Their Theoretical Investigations.

“…Therefore, the Ag + ions heavily cause environmental contamination because of increasing demand for the silver compounds in miscellaneous commercial sectors and their presence in augmented industrial sludge. [8][9][10] During such activities, silver is released into an environment that is harmful to aquatic organisms and human beings. [11][12][13] The excessive intake of silver for long term causes precipitation and leads to accumulation in eyes and skin.…”

Synthesis and Characterization of Colorimetric Metal Sensing Properties Based on Azo Chromophore Moiety

“…Dye sensors for specific chemicals are based on metal complex ligands such as crown ether, cryptand and spherand in the structures. Many interesting works have been carried out for detection of heavy metal ions [1][2][3][4]. In the context of biological and environmental aspects, heavy metal ions are considered to be highly dangerous in the human body [5,6].…”

A fluorescein derivative FLTC as a chemosensor for Hg2+ and Ag+ and its application in living-cell imaging

“…Chemosensors designed for Hg 2+ usually contains thio groups because their high affinity for Hg 2+ . A number of fluorescence chemosensors for Ag + containing receptor moiety of guanine [18] , piperazine [19] , benzoylthiourea [20] , DNA [21] , carbodithioate [22] and 1,2-diphenyldiselenide [23] have also been developed. Meanwhile there are several fluorescence chemosensors that can detect both Hg 2+ and Ag + simultaneously, but most of them cannot distinguish one from another [24][25][26][27][28][29][30][31][32] .…”
