A guanidinium modified rhodamine-based fluorescent probe for in vitro/vivo imaging of gold ions
(Royal Society of Chemistry, 2015-10-07)
We devised a rhodamine-based fluorescent probe functionalized with a guanidinium moiety, which both operates efficiently in pure aqueous media and displays a selective fluorescence response to Au3+ ions. We also demonstrated ...
Determination of force-free wet adhesion of mussel-inspired polymers to spin labeled surface
Hydration repulsive forces oppose the adhesive interactions, especially in the force-free conditions. Here, we studied spontaneous wet adhesion of 3,4-dihydroxyphenylalanine (DOPA) functionalized poly(ethylene glycol) (PEG) ...
A fluorescein-based chemodosimeter for selective gold(III) ion monitoring in aqueous media and living systems
We constructed a turn-on type chemodosimeter based upon a fluorescein scaffold for the rapid, selective detection of gold(III) ions over other metal species. This novel probe structure offers distinct features including ...
A rhodamine/BODIPY-based fluorescent probe for the differential detection of Hg(ii) and Au(iii)
(Royal Society of Chemistry, 2014-02)
We described the design and synthesis of a molecular sensor based on a rhodamine/BODIPY platform that displayed differential fluorescence responses towards Hg2+ and Au3+ and demonstrated its utility in intracellular ion imaging.
Rhodium- and palladium-catalyzed 1,5-substitution reactions of 2-En-4-yne acetates and carbonates with organoboronic acids
(American Chemical Society, 2011-08)
Two methods involving the rhodium-catalyzed reaction of 2-en-4-yne acetates and the palladium-catalyzed reaction of 2-en-4-yne carbonates with organoboronic acids were investigated; both afforded exclusively the (E)-configured ...
Palladium-catalyzed alkoxycarbonylation of (Z)-2-En-4-yn carbonates leading to 2,3,5-trienoates
(American Chemical Society, 2011-02-18)
Pd(0)-catalyzed carbonylation of (Z)-2-en-4-yn carbonates in the presence of a balloon pressure of CO in an alcohol donates vinylallenyl esters with an exclusively E-configuration and in high yields. The fact that no such ...
Rhodamine-immobilised electrospun chitosan nanofibrous material as a fluorescence turn-on Hg2+ sensor
(Wiley-VCH Verlag, 2016-04)
A turn-on fluorescence sensing system for mercuric (Hg2+) ions relying on a modified rhodamine B–chitosan fluorophore moiety was developed. This novel sensing approach relies on the simultaneous electrospinning of chitosan ...
A BODIPY/pyridine conjugate for reversible fluorescence detection of gold(III) ions
(Royal Society of Chemistry, 2015)
We designed a "turn-on" type fluorescent probe based on a BODIPY-pyridine conjugate which exhibits high selectivity towards Au(iii) ions and, also responds to changes in the pH within the acidic pH range. The probe offers ...
A BODIPY aldoxime-based chemodosimeter for highly selective and rapid detection of hypochlorous acid
(Royal Society of Chemistry, 2013-09)
A BODIPY-based fluorescent probe integrated with an aldoxime unit shows a remarkable fluorescence "turn-on" response to hypochlorous acid (HOCl). The oxidative dehydrogenation of BODIPY aldoxime by HOCl results in a distinct ...
A rhodamine based "turn-on" chemodosimeter for monitoring gold ions in synthetic samples and living cells
(Royal Society of Chemistry, 2013-07)
A rhodamine-based fluorescent probe, functionalized with an alkyne moiety, shows highly selective recognition towards Au(i) and Au(iii) ions over other metal ions. Probe 1 is successfully employed for the determination of ...
