    ABSTRACT: In this paper, a ring pair electrical resistance sensor (RPERS) has been developed for an internal-pipeline corrosion on-line monitoring system. The RPERS was divided into six segments along the circumference. The corrosion depth of each segment could be measured by using three alternating excitation currents injected into the sensor from different angles. In order to simulate and monitor the pipeline internal corrosion, a corrosion monitoring system which contained RPERS, wire electrical resistance sensor (WERS), thermocouples and a corrosion coupon was established. First, the corrosion processes in 3.5% sodium chloride solution with the temperature varied from 30°C to 60°C were studied. The temperature differences between the inner and outer pipe wall surfaces were measured by the top segment of RPERS. The test results revealed that the performance of RPERS is better than that of WERS in term of metal loss measurement. Then, carbon dioxide mixed with water vapour was pumped into the system with the temperature varied from 50°C to 80°C. In the scenarios, top of the line corrosion (TLC) occurred and was monitored by RPERS. The monitoring results demonstrated that the gas temperature and the temperature difference were important factors for TLC in sweet conditions.

    ABSTRACT: In this paper, a novel polymer film of poly(glyoxal-bis(2-hydroxyanil)) P(GBHA), was prepared by electropolymerization of glyoxal-bis(2-hydroxyanil) (GBHA) on a glassy carbon electrode (GCE), and this electrode was utilized for the simultaneous detection of the ascorbic acid (AA) and uric acid (UA). The influences of electrochemical synthesis parameters on the electron transfer properties of P(GBHA) films were investigated, and the optimum synthesis conditions providing the lowest electron transfer resistance were determined. Scanning electron microscopy (SEM), cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR) methods were employed for the characterization of the P(GBHA) film prepared under the optimum conditions. The electrochemical sensor exhibited high electrocatalytic activity toward the oxidation of AA and UA. The linear response ranges for the individual determination of AA and UA were 1.0-2000 and 1.0-200 μmol L-1 with the detection limit of 0.26 and 0.3 μmol L-1, respectively. These results present that the P(GBHA) is a promising substance for the production of electrochemical sensors with high sensitivity.

    ABSTRACT: A new chromogenic and fluorogenic probe for the discriminative signaling of sulfide and azide ions using a nitrobenzoxadiazole (NBD)-dansyl dyad 3 has been investigated. Probe 3 showed prominent colorimetric and fluorescence signaling behavior toward sulfide and azide ions in aqueous tetrahydrofuran (THF). Anion selectivity was controlled by the water content in THF. In a water rich system (H2O/THF = 99:1, v/v), probe 3 reacted mainly with sulfide ions, owing to the sulfide-selective cleavage of the NBD-OSO2Ar bond, to yield the pink-colored NBD-SH and fluorescent dansyl acid. However, in water deficient conditions (H2O/THF = 10:90, v/v), probe 3 exhibited both azide- and sulfide-selective reactions, due to the cleavage of the NBD-OSO2Ar bond, to yield either NBD-N3 (for azide ions) or NBD-SH (for sulfide ions), and dansyl acid. Azide ions can be discriminatively signaled by selective excitation at the NBD-N3 without interference from the sulfide signaling products. This selective signaling behavior is not affected by other anions that might be present in the environmental samples. To test the practical use of this probe, we created a test strip that could be used to detect sulfide and azide ions.

    ABSTRACT: Alizarin functionalized on plasmonic gold nanoparticle displays strong surface enhanced Raman scattering from the various Raman modes of Alizarin, which can be exploited in multiple ways for heavy metal sensing purposes. The present article reports a surface enhanced Raman spectroscopy (SERS) probe for trace level cadmium in water samples. Alizarin, a highly Raman active dye was functionalized on plasmonic gold surface as a Raman reporter, and then 3-mercaptopropionic acid, 2,6-pyridinedicarboxylic acid at pH 8.5 was immobilized on the surface of the nanoparticle for the selective coordination of the Cd(II). Upon addition of cadmium, gold nanoparticle provide an excellent hotspot for Alizarin dye and Raman signal enhancement. This plasmonic SERS assay provided an excellent sensitivity for cadmium detection from the drinking water samples. We achieved as low as 10 ppt sensitivity from various drinking water sources against other Alkali and heavy metal ions. The developed SERS probe is quite simple and rapid with excellent repeatability and has great potential for prototype scale up for field application.

    ABSTRACT: dl-Dithiothreitol (DTT) is used mainly in clinical and laboratorial fields. It also participates in several cellular mechanisms and can be used in some diseases treatment like cystinosis or medical conditions resulting from ion or metal toxicity. Hence, DTT detection in biological milieu is of great significance. However, most of the current fluorescent detection systems cannot discriminate DTT from single sulfhydryl-containing biothiols. Herein, a fluorescent probe for DTT has been synthesized by linking maleimide to a pyrene fluorophore. It responds to DTT or single sulfhydryl-containing thiols at different emission bands, affording it the capability to discriminately detect DTT from those thiols with single -SH. The probe responds to dithiothreitol quickly and shows high selectivity through excimer emission of pyrene moieties. As for the fluorescence intensity of the probe versus DTT concentration, two linear ranges (0-3 and 4.5-6.0 μM) can be observed, and the detection limit for DTT is 0.07 μM. Furthermore, the probe exhibits low cytotoxicity and can be successfully used in fluorescence imaging in both L929 and Hela cell lines.

    ABSTRACT: Pyrene has been widely used in designing ratiometric fluorescent probe due to its excimer emission that is different with the monomer in emission wavelengths. To take the advantage of the long-lived excimer emission, a pyrene-based zinc complex is designed as model compound for time-resolved DNA detection. PyZn exhibits excimer emission upon the binding of DNA, and the lifetime of excimer (τ > 40 ns) is one magnitude longer than that of the monomer. With a delay time of 30 ns, the monomer emission can be eliminated almost completely, leading to a much weaker background and an improved signal-to-noise ratio. Significantly, this excimer-based long-lived fluorescence is not quenched by oxygen, which provides a general strategy to design long-lived fluorescent probes for time-resolved detection in oxygenic environments and organisms.

    ABSTRACT: In this work, differential pulse cathodic stripping voltammetry method has been developed for determination of Cu (II) ions in aqueous solutions using a carbon paste electrode (CPE) modified with iodoquinol and multi-walled carbon nanotubes. The factors affecting the performance of the modified carbon paste electrode (MCPE) including the electrode composition and pH were optimized. The optimization process was performed using experimental design, artificial neural network (ANN) and genetic algorithm (GA). At first, experiments were performed using mixture design with pH factor as the process variable. The data from mixture design including experimental conditions and results were used to train the ANN using Bayesian regularization. The ANN was trained over 211 iterations with mean square error (MSE) of 1.60 and regression ocoefficient of r = 0.9328. The predicted model obtained from the trained ANN was introduced to GA as the fitness function to be optimized. GA optimized the fitness function using the defined constraints. Under optimal conditions a linear calibration graph in the range 0.01-5 μM was obtained. The square of regression coefficient was obtained 0.9880. The limit of detection (3S/N) was obtained 0.005 μM. The real samples analysis was performed to determine trace copper (II) in some oil and water specimens. The repeatability and reproducibility of method (n = 3) were obtained 3.31 and 4.12%, respectively. The shelf life of the sensor was obtained at least 4 months.

    ABSTRACT: Herein, a simple and effective electrochemical biosensor for sensitive detection of acrylamide (AA) was developed by differential pulse voltammetry (DPV) approach. This biosensor was prepared by effective self-assembling process of thiol group functionalized single-stranded DNA (ssDNA) on the surface of gold electrode (GE) through specific Au-S covalent bond. The ssDNA/GE showed a single strong DPV oxidation peak, which was used as the electrochemical signal for AA sensing. The bonding interaction between AA and ssDNA was confirmed by UV-vis absorption spectrometry and DPV. AA and ssDNA formed a single complex and the binding ratio of AA with ssDNA was one AA per guanine base of ssDNA. The electrochemical oxidation of AA-ssDNA adduct on the surface of GE was an adsorption-controlled irreversible reaction and a two-electron two-proton transfer process. Under optimum conditions, ssDNA/GE exhibited excellent DPV response depending on the concentration of AA in 0.4-200 μM range. The limit of detection was 8.1 nM (3 σ/slope). This electrochemical biosensor displayed good reproducibility and high stability. This biosensor was successfully applied to the determination of AA in tap water and potato crisps. This electrochemical platform is convenient and efficient, offering great potential for construction of electrochemical biosensors toward various toxic substances.

    ABSTRACT: A mixed-potential type NH3 sensor was fabricated using La10Si5MgO26 (LSMO) as electrolyte with both a dense layer and a porous layer and nano-structured CoWO4 as the sensing electrode. The dense LSMO electrolyte was prepared by solid state reaction method at 1500 °C via introducing Y2O3 as the sintering aid. The nano-structured CoWO4 powders were synthesized by hydrothermal method and then screen printed on the porous LSMO layer as the sensing electrode. The sensor exhibited well response-recovery characteristics to NH3 at 400-700°C. The response and recovery time were 11 and 13 s when the NH3 concentration was changed between 200 and 300 ppm, respectively. Good linear correlations between the ΔV values of the sensor and the logarithm of the NH3 concentrations for 30-300 ppm were obtained. Compared with the sensor without LSMO porous layer, the sensor with LSMO porous layer exhibited larger ΔV values and higher sensitivity due to the enhanced TPB length. The mixed-potential-model of the sensor was identified by the polarization curves in different atmospheres. The sensitivity of the sensor decreased with increasing the sintering temperature of the CoWO4 electrode, due to the growth of the CoWO4 particles. Furthermore, the present sensor also displayed small cross-sensitivities to H2, CH4 and CO2 present in the gas mixture.

    ABSTRACT: Hierarchical Sn3O4 nanoflowers, assembled from single-crystalline Sn3O4 nanosheets, were synthesized by a facile one-step hydrothermal route without any template. The crystal structure and phase purity of the Sn3O4 were investigated by X-ray diffraction (XRD). Morphologies and structures were analyzed by field-emission electron scanning microscopy (FESEM), and transmission electron microscopy (TEM), which indicated that flower-like Sn3O4 had an average size of about 700 nm and the surface of two-dimensional was smooth. BET results revealed the high surface area of the products (34.5 m2/g). The gas-sensing properties of flower-like Sn3O4 toward ethanol were investigated. Significantly, the sensor exhibited low detection limit and good repeatability to ethanol at the optimal operating temperature of 225 °C.

    ABSTRACT: We have synthesized hyaluronic acid-coated magnetic nanoparticles (HA-MNPs) to selectively collect and detect of leukemia cells (CCRF-CEM) in combination with quartz crystal microbalance (QCM) measurement. Based on the specific binding of HA with CD44 receptors overexpressed on cell surface, HA-MNPs were successfully employed for selectively extracting CCRF-CEM cells from the complex matrices including human plasma samples. The collection and detection conditions for CCRF-CEM cells were optimized. Under optimized conditions, a detection limit of 8 × 103 cells mL-1 was obtained. The HA-MNPs-based magnetic separation combined with sensitive QCM measurement provides a simple, rapid and economical method for collecting and detecting leukemia cells, and this method may have great potential for wider applications in biomedical research and clinical diagnostics.

    ABSTRACT: Multiwall carbon nanotubes (MWCNTs)/SnO2 nanocomposites containing 0.03-1.0 wt% MWCNTs were synthesized and used for the fabrication of gas sensors for ethanol, methane, CO and NO detection at low temperatures. Acid functionalized MWCNTs were dispersed in SnO2 using ultrasonic-assisted deposition-precipitation method. The nanocomposites were characterized by BET surface area measurement, FE-SEM, and XRD. The sensors response to 100 ppm ethanol, CO and NO and 1% CH4 were measured at a temperature range of 150-350 °C. The addition of carbon nanotubes causes up to 4.7 times decrease in SnO2 nanoparticles sizes. Our results indicate that 0.05 wt% is the optimum amount of carbon nanotubes, which remarkably increases the response of the SnO2-based sensors to all the gases. The most considerable response of 0.05 wt% MWCNTs/SnO2 nanocomposite sensor is related to CH4 detection, which is dramatically enhanced by a factor of 45 at 200 °C, compared to SnO2. Moreover, this sensor operating temperature for ethanol, CO and methane decrease by about 50-100 °C, upon addition of carbon nanotubes.

    ABSTRACT: This paper presents the characterization and application of prepared magnetofluorescent nanocomposites for quantitatively improving magnetic immunoassays in a thin channel. Magnetofluorescent nanocomposites [(iron oxide@polystyrene,QDg@mSiO2)@SiO2] were characterized for optimizing magnetic and fluorescence properties for multifunctional applications. The prepared magnetofluorescent nanocomposites have several times higher magnetism than those of literature and exhibit strong fluorescence. The number of magnetofluorescent nanocomposites with primary antibody can be reliably estimated through fluorescence measurement and used for a sandwich immunoassay. We used a model biomarker, tumor necrosis factor-α (TNF-α), to demonstrate the feasibility of method. The detection limit of TNF-α was 1.0 pg/ml and the linear range was 1.7 pg/ml to 17 ng/ml. This detection limit was substantially lower and the linear range was considerably wider than those of an enzyme-linked immunosorbent assay (ELISA) and other methods in sandwich immunoassays. The differences between our method and an ELISA for TNF-α measurements of serum samples were less than 11%. The results show that magnetofluorescent nanocomposites are useful to provide higher quantitative accuracy and wider linear range than those of previous methods with 50% of the biofunctional nanocomposites, enabling the simple, rapid, and sensitive detection of biomarkers.
