Sensitivity evaluation of rhodamine B hydrazide towards nitric oxide and its application for macrophage cells imaging

Design and synthesis of a novel chromium(III) selective fluorescent chemosensor bearing a thiodiacetamide moiety and two rhodamine B fluorophores

“…Therefore, various fluorophores with different excitation and emission wavelengths, such as coumarin [30,31], pyrene [32,33], 1, 8-naphthalimide [34,35], xanthenes [36,37], squaraine [38], cyanine [39], boron dipyrromethene difluoride (BODIPY) [40], and nitrobenzofurazan [41], have been employed to develop various chemical sensors. Among the developed fluorophores, rhodamine and its derivatives [42,43] employ an ideal framework in the construction of fluorescent probes due to their excellent spectroscopic properties including high fluorescence quantum yield, large molar extinction coefficient, and visible wavelength excitation [44][45][46][47]. Based on the principle of metal coordination-induced spirolactam ring-opening of rhodamine, a large number of probes have been reported for the detection of various metal ions, such as Fe 3+ , Hg 2+, Cu 2+ , Sn 4+ , Sn 2+ , Zn 2+ , Pb 2+ , and Cd 2+ [48][49][50][51][52][53][54][55].…”

Microchip electrophoresis with amperometric detection for the study of the generation of nitric oxide by NONOate salts

“…Many approaches for the detection of NO in vivo have been reported in the literature. These include the reaction of NO with fluorescent probes [2–8], direct amperometric detection [9–11], chemiluminescence [12], electron paramagnetic resonance [8, 11], voltammetry [13], and indirect detection of its degradation products nitrite and nitrate [14–17]. …”

Nitric oxide in plants: an assessment of the current state of knowledge

“…In a comprehensive assessment of the specificity of rhodamine B dyes, the fluorescence response was greatest with NO and ONOO − . However, fluorescence was also significant with hydroxyl radicals (Wu et al 2011), which are likely to be generated in stressed plants (Apel and Hirt 2004). Europium(III) chelate has recently been advanced as an NO fluorescent probe but its wider specificities are yet to be fully assessed (Chen et al 2011).…”
