“…where C UA is the UA concentration, and I and I 0 (see Figure 6D) denote the fluorescence intensity of the AgNPs/N-CQDs in the presence and absence of UA, respectively. Thus, a good correlation coefficient (R 2 ) of 0.9971 was obtained in addition to a UA detection limit of 0.53 µmol/L, and the relative standard deviation (RSD, n = 5) was <1.2% at a UA concentration of 10.0 µmol/L, which is comparable with the response ranges and UA limits of detection (LODs) detected reported for previous fluorescence methods [30][31][32][33][34][35][36][37] (Table 1), thereby revealing that our probe based on AgNPs/N-CQDs exhibits an outstanding performance.…”

The fabrication of efficient fluorescent probes that possess an excellent sensitivity and selectivity for uric acid is highly desirable and challenging. In this study, composites of silver nanoparticles (AgNPs) wrapped with nitrogen-doped carbon quantum dots (N-CQDs) were synthesised utilising N-CQDs as the reducing and stabilising agents in a single reaction with AgNO3. The morphology and structure, absorption properties, functional groups, and fluorescence properties were characterised by transmission electron microscopy, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, ultraviolet spectroscopy, fluorescence spectroscopy, and X-ray diffraction spectroscopy. In addition, we developed a novel method based on AgNPs/N-CQDs for the detection of uric acid using the enzymatic reaction of uric acid oxidase. The fluorescence enhancement of the AgNPs/N-CQDs composite was linear (R2 = 0.9971) in the range of 2.0–60 μmol/L, and gave a detection limit of 0.53 μmol/L. Trace uric acid was successfully determined in real serum samples from the serum of 10 healthy candidates and 10 gout patients, and the results were consistent with those recorded by Qianxinan Prefecture People’s Hospital. These results indicate that the developed AgNP/N-CQD system can provide a universal platform for detecting the multispecies ratio fluorescence of H2O2 generation in other biological systems.

“…Оптические свойства РЗИ обусловливают активное использование наночастиц на их основе для различных биомедицинских приложений, в том числе для оптической визуализации. В настоящее время большинство исследований посвящено материалам, допированным ионами Eu 3+ , Tb 3+ и Dy 3+ , которые имеют интенсивные полосы люминесценции [49,168,169]. Необходимо подчеркнуть, что одним из основных недостатков люминесцентной оптической визуализации является то, что наиболее эффективное поглощение энергии наночастицами обычно происходит в ультрафиолетовой или видимой областях, что может вызвать автофлуоресценцию клеток и тканей.…”

Luminescent nanomaterials doped with rare-earth elements are characterized by such physicochemical properties as long-lived luminescence, large Stokes or anti-Stokes shifts, narrow emission bands, high photostability and low toxicity. These materials can be considered as a new generation of biosensors along with conventional molecular probes, such as organic dyes, quantum dots and chelate-based lanthanide probes. In recent years there has been significant interest in the study of functional nanomaterials based on rare earth elements. The purpose of this paper is to provide an overview of recent advances in the development of luminescent inorganic nanoparticles doped with rare earth elements which could be used for biomedical applications.

“…Intramolecular energy transfer from the excited triplet states of the ligand to Tb 3+ ions in chelate results in an intensive fluorescence with a large stoke shift. Some coordination complexes of Tb 3+ have been proposed as fluorescent probes for sensing small organic molecules, aromatic compounds, ions, and vapors [4][5][6][7][8][9][10][11][12][13]. Altunbas' group [4] suggested Ochratoxin A (OTA) sensor based on the coordination of OTA to Tb 3+ ions, which were attached to the EDTA modified SiO 2 nanoparticles, resulted in the enhancement of the fluorescence intensity of Tb 3+ .…”

“…A porous network polymer was coordinated with Tb 3+ ions to create a ratiometric fluorescent sensor for detecting dipicolinic acid, in which dipicolinic acid played as an "antenna" and transferred its absorbed energy to Tb 3+ ions to result in enhancement of Tb 3+ fluorescence intensity [8]. Using the aggregation-induced fluorescence of Tb 3+ -luminol as an "electron donor" to uric acid, Qi's group suggested a uric acid sensor based on the photoinduced electron transfer effect to result in a quenching of fluorescence intensity of the complex [12]. Spermine (SP), a polyamine presents in fluids and eukaryotic cells of many living organisms.…”

We developed a facile detection method of spermine based on the fluorescence (FL) quenching of the ciprofloxacin-Tb3+ complex, which shows astrong green emission. Ciprofloxacin (CP) makes efficient bondings to Tb3+ ion as a linker molecule through carboxylic and ketone groups to form a kind of lanthanide coordination polymer. The addition of spermine that competes with Tb3+ ions for the interaction with CP due to its positive charge brings about weakened coordination linkage of CP and Tb3+. The probe exhibited high sensitivity, selectivity, and good linearity in the range of 2–180 μM with a low limit of detection of 0.17 μM. Moreover, we applied this method on the paper strip test (PST), along with the integration of a smartphone and Arduino-based device. The practical reliability of the developed probe was evaluated on human serum samples with acceptable analytical results.
