Monoterpenoid derivative based ratiometric fluorescent chemosensor for bioimaging and intracellular detection of Zn2+ and Mg2+ ions

Simple Fluorescence Turn-On Chemosensor for Selective Detection of Ba2+ Ion and Its Live Cell Imaging

“…Next, cells were gently washed three times with PBS to eliminate the traces of 4PB and culture media. Formaldehyde solution (3.7%, pH 7.0) was used to fix the cells, and images of cells were captured by a fluorescence microscope under green and red filters installed at the Center for University-Wide Research Facilities (CURF) at Chonbuk National University (CBNU, Jeonju, South Korea) …”

The ligand 4PB was synthesized via simple synthetic methods as described in Scheme 1.…”

Selective Detection of Mg2+ for Sensing Applications in Drinking Water

“…Among the analytical procedures able to track Mg 2+ ions, the employment of optical chemosensors represents an efficient strategy that offers advantages on instrumental methods and rests on simplicity, reliability, velocity and possibility to operate in real time conditions [4–10] . However, most chemosensors reported so far are not able to distinguish between Mg 2+ and other metal cations, especially Ca 2+ and Zn 2+ [11–18] . The availability of chemosensors that offer selectivity for Mg 2+ vs. Ca 2+ thus represents a remarkable analysis tool, both for biological and environmental samples.…”

“…[4][5][6][7][8][9][10] However, most chemosensors reported so far are not able to distinguish between Mg 2 + and other metal cations, especially Ca 2 + and Zn 2 + . [11][12][13][14][15][16][17][18] The availability of chemosensors that offer selectivity for Mg 2 + vs. Ca 2 + thus represents a remarkable analysis tool, both for biological and environmental samples. To this purpose, the development of all-solid-state, disposable and low-cost optical sensors permitting the fast and selective Mg 2 + detection without the employment of expensive equipment, complex sample preparations and skilled operators involvement is an attractive, as far a challenging analytical task.…”

A reversible calix[4]arene armed phenolphthalein based fluorescent probe for the detection of Zn2+ and an application in living cells

“…Recently, fluorescence chemosensors were used for this purpose due to the many advantages such as high sensitivity, low cost, reproducibility, simplicity and instantaneous response . Although imagination of Zn 2+ in vitro and/or in vivo is applied by a variety of fluorescent sensors for Zn 2+ , there is still a challenging task present in the successful discernment of Zn 2+ and cadmium ion (Cd 2+ ), because these cations display very similar chemical properties and photo physical changes in sensing studies since they are located in the same group of the periodic table .…”
