Electrochemical detection of dopamine in the presence of ascorbic acid using graphene modified electrodes.
The synthesis of graphene using a modified Hummer's method and its application for the electrochemical detection of dopamine was reported and the capacity of graphene modified electrode for selective detection of serotonin was confirmed in a sufficient amount of ascorbic acid. Expand
Calixarene-derived fluorescent probes.
Fluoro- and chromogenic chemodosimeters for heavy metal ion detection in solution and biospecimens.
Duong Tuan Quang was born in 1970 in Thanhhoa, Vietnam, and graduated from Hue University in 1992, where he obtained his M.S. degree in Chemistry and went to Korea University as a research professor in 2010, where his main task involved the development of chromogenic and fluorogenic molecular sensors to detect specific cations and anions.

Small molecule-based ratiometric fluorescence probes for cations, anions, and biomolecules.
An overview of the design principles underlying small fluorescent probes that have been applied to the ratiometric detection of various analytes, including cations, anions, and biomolecules in solution and in biological samples are provided. Expand
Coumarin-derived Cu(2+)-selective fluorescence sensor: synthesis, mechanisms, and applications in living cells.
A novel coumarin-based fluorogenic probe bearing the 2-picolyl unit was developed as a fluorescent chemosensor with high selectivity and suitable affinity in biological systems toward Cu(2+) over other cations tested, and results indicate that 1 should be useful for the fluorescence microscopic imaging and the study on the biological functions of Cu( 2+.
