“…The complex between europium(III) and gatifloxacin in a co-luminiscence system Eu 3+ -La 3+ -gatifloxacin-sodium dodecylbenzene sulfonate was used for the determination of trace amounts of Eu 3+ in rare earth samples [217]. Quencing fluorescence of a terbium chelates in the presence of Hg 2+ was used for development of a highly sensitive and specific detection method of trace Hg 2+ in trace Hg 2+ in biological samples (urine) and environmental water [218].…”

Quinolones are synthetic broad-spectrum antibiotics with good oral absorption and excellent bioavailability. Due to the chemical functions found on their nucleus (a carboxylic acid function at the 3-position, and in most cases a basic piperazinyl ring (or another N-heterocycle) at the 7-position, and a carbonyl oxygen atom at the 4-position) quinolones bind metal ions forming complexes in which they can act as bidentate, as unidentate and as bridging ligand, respectively. In the polymeric complexes in solid state, multiple modes of coordination are simultaneously possible. In strongly acidic conditions, quinolone molecules possessing a basic side nucleus are protonated and appear as cations in the ionic complexes. Interaction with metal ions has some important consequences for the solubility, pharmacokinetics and bioavailability of quinolones, and is also involved in the mechanism of action of these bactericidal agents. Many metal complexes with equal or enhanced antimicrobial activity compared to the parent quinolones were obtained. New strategies in the design of metal complexes of quinolones have led to compounds with anticancer activity. Analytical applications of complexation with metal ions were oriented toward two main directions: determination of quinolones based on complexation with metal ions or, reversely, determination of metal ions based on complexation with quinolones.

“…Ligand-sensitized luminescence of lanthanide has a relevant interest to analytical chemists due to its potential applications in biochemistry and luminescent analysis of biochemical drugs as well as for the trace determination of lanthanide ions and some organic analytes [26]. Therefore, some optical methods for the measurement of absorption, reflectance or luminescence of certain materials have been improved [25].…”

Polymers from natural sources are particularly useful as biomaterials for medical devices applications. In this study, the results of characterization of a gelatin network electrolyte doped with europium triflate (Eu(CF 3 SO 3 ) 3 ) are described. The unusual electronic properties of the trivalent lanthanide ions make them well suited as luminescent reporter groups, with many applications in biotechnology. Samples of solventfree electrolytes were prepared with a range of guest salt concentration. Materials based on Eu(CF 3 SO 3 ) 3 were obtained as mechanically robust, flexible, transparent, and completely amorphous films. Samples were characterized by thermal analysis (thermogravimetry analysis (TGA) and differential scanning calorimetry (DSC), electrochemical stability, scanning electron microscopy (SEM), and photoluminescence spectroscopy.

“…In order to explain the luminescence enhancement mechanism, the group recorded UV-absorption spectra, determined the surface tension and the microviscosity of the aqueous system and concluded that the quaternary complex was formed in a highly viscous and hydrophobic medium with no water molecules to quench the luminescence through radiationless vibrations. Therefore, the complex was able to fully transform the absorbed energy into luminescence [165].…”

Quinolones comprise a series of synthetic bactericidal agents with a broad spectrum of activity and good bioavailability. An important feature of these molecules is their capacity to bind metal ions in complexes with relevant biological and analytical applications. Interestingly, lanthanide ions possess extremely attractive properties that result from the behavior of the internal 4f electrons, behavior which is not lost upon ionization, nor after coordination. Subsequently, a more detailed discussion about metal complexes of quinolones with lanthanide ions in terms of chemical and biological properties is made. These complexes present a series of characteristics, such as narrow and highly structured emission bands; large gaps between absorption and emission wavelengths (Stokes shifts); and long excited-state lifetimes, which render them suitable for highly sensitive and selective analytical methods of quantitation. Moreover, quinolones have been widely prescribed in both human and animal treatments, which has led to an increase in their impact on the environment, and therefore to a growing interest in the development of new methods for their quantitative determination. Therefore, analytical applications for the quantitative determination of quinolones, lanthanide and miscellaneous ions and nucleic acids, along with other applications, are reviewed here.
