Abstract
The smaller, the more fluorescent: The hydrothermal reaction of phenol with hexamethylenetetramine (HMT) leads to two morphologies of phenol formaldehyde resin (PFR), namely, bigger nanoparticles with feeble green fluorescence and smaller amorphous polymers with strong blue-green fluorescence. It reveals that both of them are doped with nitrogen, and the blue-green photoluminescent polymer is confirmed to sense ferric ion (Fe(3+) ) with high selectivity.

Abstract
In this study, a multiplex fluorescence sensor for successive detection of Fe(3+), Cu(2+) and Hg(2+) ions based on "on-off" of fluorescence of a single type of gold nanoclusters (Au NCs) is described. Any of the Fe(3+), Cu(2+) and Hg(2+) ions can cause quenching fluorescence of Au NCs, which established a sensitive sensor for detection of these ions respectively. With the introduction of ethylene diamine tetraacetic acid (EDTA) to the system of Au NCs and metal ions, a restoration of fluorescence may be found with the exception of Hg(2+). A highly selective detection of Hg(2+) ion is, thus, achieved by masking Fe(3+) and Cu(2+). On the other hand, the masking of Fe(3+) and Cu(2+) leads to the enhancement of fluorescence of Au NCs, which in turn provides an approach for successive determination of Fe(3+) and Cu(2+) based on "on-off" of fluorescence of Au NCs. Moreover, this assay was applied to the successful detection of Fe(3+), Cu(2+) and Hg(2+) in fish, a good linear relationship was found between these metal ions and the degree of quenched fluorescent intensity. The dynamic ranges of Hg(2+), Fe(3+) and Cu(2+) were 1.96×10(-10)-1.01×10(-9), 1.28×10(-7)-1.27×10(-6) and 1.2×10(-7)-1.2×10(-6) M with high sensitivity (the limit of detection of Fe(3+) 2.0×10(-8) M, Cu(2+) 1.9×10(-8) M and Hg(2+) 2×10(-10) M). These results indicate that the assay is suitable for sensitive detection of these metal ions even under the coexistence, which can not only determine all three kinds of metal ions successively but also of detecting any or several kinds of metal ions.

Abstract
Carbon quantum dots (C-Dots) have drawn extensive attention in recent years due to their stable physicochemical and photochemical properties. However, the development of nitrogen-doped carbon quantum dots (N-doped C-Dots) is still on its early stage. In this paper, a facile and high-output solid-phase synthesis approach was proposed for the fabrication of N-doped, highly fluorescent carbon quantum dots. The obtained N-doped C-Dots exhibited a strong blue emission with an absolute quantum yield (QY) of up to 31%, owing to fluorescence enhancement effect of introduced N atoms into carbon dots. The strong coordination of oxygen-rich groups on N-doped C-Dots to Fe(3+) caused fluorescence quenching via nonradiative electron-transfer, leading to the quantitative detection of Fe(3+). The probe exhibited a wide linear response concentration range (0.01-500 μM) to Fe(3+) with a detection limit of 2.5 nM. Significantly, the N-doped C-Dots possess negligible cytotoxicity, excellent biocompatibility, and high photostability. All these features are favorable for label-free monitoring of Fe(3+) in complex biological samples. It was then successfully applied for the fluorescence imaging of intracellular Fe(3+). As an efficient chemosensor, the N-doped C-Dots hold great promise to broaden applications in biological systems.

Abstract
With increasing trends of global population growth, urbanization, pollution over-exploitation, and climate change, the safe water supply has become a global issue and is threatening our society in terms of sustainable development. Therefore, there is a growing need for a water-monitoring platform with the capability of rapidness, specificity, low-cost, and robustness. This review summarizes the recent developments in the design and application of gold nanoparticles (AuNPs) based optical assays to detect contaminants in aqueous media with a high performance. First, a brief discussion on the correlation between the optical reading strategy and the optical properties of AuNPs is presented. Then, we summarize the principle behind AuNP-based optical assays to detect different contaminants, such as toxic metal ion, anion, and pesticides, according to different optical reading strategies: colorimetry, scattering, and fluorescence. Finally, the comparison of these assays and the outlook of AuNP-based optical detection are discussed.

Abstract
A simple, one-step facile route for preparation of water soluble and fluorescent Cu nanoclusters (NCs) stabilized by tannic acid (TA) is described. The as-prepared TA capped Cu NCs (TA-Cu NCs) are characterized by UV-vis spectroscopy, Fourier transform infrared (FT-IR) spectroscopy, luminescence, transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). The TA-Cu NCs show luminescence properties having excitation and emission maxima at 360 nm and 430 nm, respectively, with a quantum yield of about 14%. The TA-Cu NCs are very stable even in 0.3 M NaCl, and their luminescent properties show pH independent. The fluorescence (FL) of Cu NCs is strongly quenched by Fe(3+) through an electron transfer mechanism, but not by other metal ions. Furthermore, the FL of the TA-Cu NCs shows no changes with the addition of Fe(2+) or H2O2 individually. On this basis, a facile chemosensor was developed for rapid, reliable, sensitive, and selective sensing of Fe(3+) ions with detection limit as low as 10 nM and a dynamic range from 10 nM to 10 μM. The proposed sensor was successfully used for the determination of iron contents in serum samples. Importantly, the Cu NCs-based FL probe showed long-term stability, good biocompatibility and very low cytotoxicity. It was successfully used for imaging ferric ions in living cells, suggesting the potential application of Cu NCs fluorescent probe in clinical analysis and cell imaging.

Abstract
We report a direct one-pot approach, employing 11-mercaptoundecanoic acid (11-MUA) as a reducing and capping agent, for the preparation of fluorescent Ag/Au bimetallic nanoclusters (Ag/AuNCs) from HAuCl4 and AgNO3 in basic aqueous solution at room temperature. Unlike the monocomponent 11-MUA-AgNCs with negligible fluorescence, the as-prepared 11-MUA-Ag/AuNCs exhibit similar average diameters of ∼1.8 nm but much stronger and tunable fluorescence by varying the concentration ratios of AgNO3 to HAuCl4 in the synthesis. The quantum yield of the 11-MUA-Ag/AuNCs can reach 6.81% at a Ag-to-Au molar ratio of 1 : 2, nearly 3-fold higher than the monocomponent 11-MUA-AuNCs (2.38%) of similar sizes. More importantly, the occurrence of the reaction between Ag(+) ions and Au(0) of 11-MUA-AuNCs (which is opposite to the classic galvanic theory) and the coexistence of Ag(0) and Au(+) in the final NC products, are revealed by thorough analysis of XPS data. The anti-galvanic reduction, that is, metal ions are replaced by less reactive metals, has been further demonstrated through the reaction between the as-obtained purified monocomponent 11-MUA-AuNCs and Ag(+) ions. Direct electrochemical insights into the anti-galvanic reduction mechanism were provided by cyclic voltammetry characterizations of the NCs, and the universality of the anti-galvanic reduction was tested by preparing thiolated Pt/Au bimetallic NCs using platinum instead of silver in our synthetic system.

Abstract
A novel organic-inorganic hybrid sensor based on diethylenetriaminepentaacetic acid (DTPA) modified reduced graphene oxide (RGO-DTPA) chelated with terbium ions allows detection of dopamine (DA) through an emission enhancement effect. Its luminescence, peaking at 545 nm, has been improved by a factor of 25 in the presence of DA (detection limit = 80 nM). In addition, this covalently bonded terbium complex functionalized reduced graphene oxide (RGO-DTPA-Tb) can be successfully assembled on a glassy carbon electrode. The assay performed through differential pulse voltammetry (DPV) yielded obvious peak separation between DA and excessive amounts of the interfering ascorbic acid (AA).

Abstract
An innovative and green strategy to synthesize carbon dots (CDs) with a quantum yield (QY) of nearly 19.8% has been successfully established for the first time. Subsequently, the possible fluorescence (FL) mechanism was elucidated by fluorescence, UV-vis, high resolution transmission electron microscope (HR-TEM), Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) analyses. Significantly, not only the precursor of CDs and whole synthesis procedure was green, but also the CDs obtained here exhibited various advantages including high fluorescent QY, excellent photostability, non-toxicity and satisfactory stability. Additionally, the CDs were employed for assaying Fe(3+) based on direct interactions between Fe(3+) and − COOH, − OH and − NH2 of CDs, resulting in aggregations that facilitate to quench their fluorescence. The decrease of fluorescence intensity permitted detections of Fe(3+) in a linear range of 5.0 × 10(-9)-1.0 × 10(-4)mol/L, with a detection limit of 1.7 × 10(-9)mol/L at a signal-to-noise ratio of 3, suggesting a promising assay for Fe(3+). Eventually, the CDs were applied for cell imaging and coding, demonstrating their potential towards diverse applications.

Abstract
Carbon dots (C-dots) have been proven to show the capability for direct reduction of Ag(+) to elemental silver (Ag(0)) without additional reducing agent or external photoirradiation by incubating Ag(+) with C-dots for 5 min in a water bath at 50 °C. Silver nanoparticles (Ag-NPs) are simultaneously formed with an average size of 3.1 ± 1.5 nm and grew on carbon dots. This process involves the oxidation of amine or phenol hydroxyl groups on the aromatic ring of C-dots. Meanwhile C-dots protect and stabilize the Ag-NPs from aggregation in aqueous medium; that is, the Ag-NPs are stable at least for 45 days in aqueous medium. The formed Ag-NPs cause significant resonance light scattering (RLS), which correlates closely with the concentration of silver cation, and this facilitates quantitative detection of silver in aqueous medium.

Abstract
A rhodamine-based "turn-on" fluorescent probe 1 was synthesized with high yield. The recognizing behavior displays high selectivity of 1 toward Fe(2+) with a 2:1 complex, and 1 exhibits a stable response for Fe(2+) over a concentration range from 2 μM to 24 μM. Most importantly, probe is hardly interfered by other transition metal ions. Their fluorescent enhancement is observed in the presence of Fe(2+) because of the ring-open interactions of spirocyclic. All measurements are made in PBS buffer environments simulating biological conditions to make them suitable candidates for fluorescent labeling of biological systems. Confocal laser scanning microscopy experiments have proven that probe can be used to monitor Fe(2+) in living cells.

Abstract
In the past few years, highly luminescent noble metal nanoclusters (e.g., Au and Ag NCs or Au/Ag NCs in short) have emerged as a class of promising optical probes for the construction of high-performance optical sensors because of their ultrasmall size (<2 nm), strong luminescence, good photostability, excellent biocompatibility, and unique metal-core@ligand-shell structure. In this Focus Review, we briefly summarize the common syntheses for water-soluble highly-luminescent thiolate- and protein-protected Au/Ag NCs and their interesting luminescence properties, highlight recent progress in their use as optical sensors with an emphasis on the mechanisms underlying their selectivity, and finally discuss approaches to improving their sensitivity. The scope of the works surveyed is confined to highly luminescent thiolate- and protein-protected Au/Ag NCs.

Poly(1-amino-5-chloroanthraquinone): highly selective and ultrasensitive fluorescent chemosensor for ferric ion. J Fluoresc 2013; 23:621-7.

Abstract
Poly(1-amino-5-chloroanthraquinone) (PACA) was firstly synthesized by a chemically oxidative interfacial polymerization. The PACA has been developed as a fluorescent sensor for the determination of Fe(III) in semi-aqueous solution at pH 7.0. The sensor exhibited remarkably high sensitivity toward Fe(3+) since the fluorescence of the polymer could be significantly quenched even though trace Fe(3+) was added. The sensor showed a linear fluorescence emission response over a wide concentration range from 1.0 × 10(-10) to 1.0 × 10(-4) M, with an ultra-low detection limit of 2.0 × 10(-11) M. The quenching of the fluorescence was found to be static one due to the formation of non-fluorescent complex in the ground state.

Facile preparation of glutathione-stabilized gold nanoclusters for selective determination of chromium (III) and chromium (VI) in environmental water samples. Anal Chim Acta 2013; 770:140-6. [PMID: 23498696 DOI: 10.1016/j.aca.2013.01.042] [Citation(s) in RCA: 85] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2012] [Revised: 01/14/2013] [Accepted: 01/20/2013] [Indexed: 11/22/2022]
Abstract
A novel method for selective determination of Cr(III) and Cr(VI) in environmental water samples was developed based on target-induced fluorescence quenching of glutathione-stabilized gold nanoclusters (GSH-Au NCs). Fluorescent GSH-Au NCs were synthesized by a one-step approach employing GSH as reducing/protecting reagent. It was found that Cr(III) and Cr(VI) showed pH-dependent fluorescence quenching capabilities for GSH-Au NCs, and thus selective determination of Cr(III) and Cr(VI) could be achieved at different pHs. Addition of EDTA was able to effectively eliminate the interferences from other metal ions, leading to a good selectivity for this method. Under optimized conditions, Cr(III) showed a linear range of 25-3800 μg L(-1) and a limit of detection (LOD) of 2.5 μg L(-1). The Cr(VI) ion demonstrated a linear range of 5-500 μg L(-1) and LOD of 0.5 μg L(-1). The run-to-run relative standard deviations (n=5) for Cr(III) and Cr(VI) were 3.9% and 2.8%, respectively. The recoveries of Cr(III) and Cr(VI) in environmental water samples were also satisfactory (76.3-116%). This method, with its simplicity, low cost, high selectivity and sensitivity, could be used as a promising tool for chromium analysis in environmental water samples.
