Determination of ciprofloxacin and enrofloxacin by the sensitized fluorescence of europium in the presence of the second ligand and micelles of anionic surfactants

Interfacial interactions of hard polyelectrolyte-stabilized luminescent colloids with substrates

“…A plenty of biorelevant substrates are chelating ligands able to complex with lanthanides [8][9][10]. Literature data represent fine examples of luminescent sensing of phosphates [10] and antibiotics [11][12][13][14][15] through a sensitization of lanthanide-centered luminescence in aqueous solutions.…”

Detection of Ciprofloxacin in Urine through Sensitized Lanthanide Luminescence

“…Cipro, being a representative quinolone carboxylic acid derivative, shows native fluorescence emission at 440 nm (Φ F = 0.28) upon excitation at 278 nm in water [13]. Based on the native fluorescence of Cipro, a number of detection methods are reported such as spectrophotometry [17], spectrofluorimetry [18,19], and flow-injection with chemiluminescence detection [20,21]. In those existing methods a sample separation process is also necessary to remove proteins, amino acids and other biomolecules that interfere with the detection signal.…”

Impact of l-leucine on controlled release of ciprofloxacin through micellar catalyzed channels in aqueous medium

“…Yang et al studied the effect of surfactants, cyclodextrins and pH on the fluorescence profile of CIP and have shown that the three acid constant of CIP are very close to each other due to which and there is not much effect on the fluorescence intensity of CIP in the pH range of 2-7 [9]. In other studies, the micellar effect is utilized for the effective determination of CIP and some other fluoroquinolones [14][15][16][17].…”
