Lanthanide materials as chemosensors

Luminescent and time-resolved determination of gemifloxacin mesylate in pharmaceutical formulations and spiked blood plasma samples using a lanthanide complex as a probe

“…Moreover, GMF acts as an antenna to transfer its emission energy to the ion. [26][27][28][29] The development of efficient lanthanide complexes is a signicant research focus, in with several groups are engaged. [30][31][32][33][34][35] As a result, many lanthanide chelates have been investigated to serve as valuable alternatives to traditional uorophores in luminescence applications.…”

Thin Films of Lanthanide Stearates as Modifiers of the Q-Sense Device Sensor for Studying Insulin Adsorption

“… 6 At the same time, ions of trivalent cations tend to hydrolysis and complexation more than divalent metals in an overwhelming number of cases; therefore, this problem is more relevant for trivalent ions. In this regard, works on these lanthanide salts were published much later, in spite of the fact that the production of such films was described in literature 7 and results of the preparation multilayer LBF from acids and trivalent metals were reported. 8 , 9 The techniques often used to obtain these structures are not standard and have only been studied for a small number of trivalent cations.…”

Yttrium stearate was studied in ref , where it was shown that the ion fraction form of the yttrium content in the film depends on the pH of the subphase.…”

Fluorescent Polyimide in Sensing Applications

“…A chemical sensor converts chemical information into an electrical signal to provide a qualitative or quantitative representation of chemical composition and activity. Chemical sensors create signals by selectively binding a sensing material to an analyte, using a sensing element and a transducer [1]. A sensor's characteristics are dependent upon chemical species that interact with it.…”
