Sensitive luminescent determination of DNA using the terbium(III)–difloxacin complex

Development and Validation of A Spectrofluorimetric Determination of Calf Thymus DNA Using a Terbium-Danofloxacin Probe

“…In recent years, the coordination complexes of metal ions especially rare earth ions as a probe to study DNA have attracted much attention. [19][20][21][22][23][24][25] Here we employed the fluorescence of terbiumdanofloxacin (Tb 3+ -Dano) complex as a probe for the determination of calf thymus DNA (ctDNA).…”

“…12 The specific strong fluorescence of lanthanides as a result of an efficient intra molecular energy transfer from the excited triplet state of the antenna ligand to the emitting electronic level of the lanthanide ion possesses luminescence characteristics of narrow spectral width, long luminescence lifetime, large Stock's shifts (> 200 nm) and µs-luminescence decay times. 13,14 Tb 3+ ions for their resonance energy levels overlap with ultraviolet light, often used as the fluorescence probes to determine several classes of organic compounds because of the high fluorescence quantum efficiency of their chelates. 13 There are many luminescence probes for the determination of DNA.…”

Luminescence probes including organic dyes, 15,16 metal complex compounds 17 and lanthanide ions 18 are used for improving sensitivity in determining nucleic acids.…”

Ag Nanoparticles-enhanced Fluorescence of Terbium-Deferasirox Complexes for the Highly Sensitive Determination of Deferasirox

“…[12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29] However, a further improvement of sensitivity of these methods would allow the detection of even lower analyte concentrations. Therefore, the combination of amplification strategies with lanthanide luminescence is a highly promising approach.…”

Spectrofluorimetric determination of buparvaquone in biological fluids, food samples and a pharmaceutical formulation by using terbium–deferasirox probe

“…The sensitisation of lanthanide ions luminescence -especially terbium and europium ions -by organic ligands, has been widely employed in some applications, such as the investigation of the function of nucleic acids, immunoassays, determination of organic compounds and chromatographic and electrophoretic detections (Dehghan et al, in press;Ioannou, Rusakova, Andrikopoulou, Glynou, & Tzompanaki, 1998;Leonard & Gunnlaugsson, 2005;Manzoori et al, in press;Miao, Liu, Hou, & Jiang, 2006;Yegorova et al, 2007;Yu, Li, & Chen, 2007), also it has been applied in food and beverage industries for determination of phenolic compounds in wine, fruit juice and tea (Andreu-Navarro, Russo, AguilarCaballos, Fernández-Romero, & Gómez-Hens, 2011;Shaghaghi, Manzoori, & Jouyban, 2008), terephthalic acid in drink samples (Caro de la Torre & Gómez-Hens, 2000), nicotinic acid and nicotinamide in food and pharmaceutical samples (Krasnova, Aguilar-Caballos, & Gómez-Hens, 2001) and lasalocid in drinking water, poultry feed and chicken liver samples (Aguilar-Caballos, Gómez-Hens, & Pérez-Bendito, 1999).…”
