Surface-modified CdS quantum dots as luminescent probes for sulfadiazine determination

A simple fluorescence quenching method for roxithromycin determination using CdTe quantum dots as probes

“…2 we can observe a red-shift with increase in concentration of ROX on the emission spectra maximum. Thus, we believe that the ROX binding to the CdTe quantum dots made the surface of the particles change, which induce the quench of QDs fluorescence [10,17].…”

“…Compared to organic fluorophores, QDs exhibit higher quantum yield, color availability, good photostability, large surface-to-volume ratio, and surface functionality. Thus, QDs possess highly attractive fluorescent properties to be ideal fluorescent indicators for chemical and biological assay, recently especially in analytical chemistry [9][10][11][12][13].…”

A rapid and sensitive assay for determination of doxycycline using thioglycolic acid-capped cadmium telluride quantum dots

“…Generally, quantum dots with capping ligands have been used in highly-sensitive bioanalytical assays such as detection and labeling of biomolecules [25][26][27][28]. Because of their outstanding optical properties, they have been widely used in the analysis of pharmaceutical such as paeonol [29], roxithromycin [30], ellagic acid [31], rifampicin [32], oxytetracycline [28] and sulfadiazine [33]. These studies have revealed that the interactions between thioglycolic acid capped quantum dots (TGA/QDs) and some substances could moderate the photophysical properties of QDs.…”

CdTe Quantum Dots as Fluorescent Probes for Josamycin Determination

“…Compared to organic fluorophores, QDs exhibit higher quantum yield, colour availability, good photostability, large surface-to-volume ratio and surface functionality. Thus, QDs have been widely employed in some applications, such as the determination of enrofloxacin, 15 ranitidine hydrochloride, 16 roxithromycin,…”
