    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: An electrochemical immunosensor for the detection of hemagglutinin from avian influenza virus H5N1 is presented in this paper. The following steps lead up to the construction of immunosensor: (i) modification of gold electrodes with 4,4′-thiobisbenzenethiol, (ii) modification of self-assembled monolayer of 4,4′-thiobisbenzenethiol with gold colloidal nanoparticles, (iii) immobilization of single chain variable fragments of antibodies (scFv) against hemagglutinin H5 via SAu covalent bonds, (iv) blocking of the remaining free space with bovine serum albumin. The interactions between the scFv and hemagglutinin variants have been explored with electrochemical impedance spectroscopy in the presence of [Fe(CN)6]3−/4− as an electroactive marker. The immunosensor was able to detect two different His-tagged variants of recombinant hemagglutinin from H5N1 viruses: the short fragment (17–340 residues) of A/swan/Poland/305-135V08/2006 and the long (17–530 residues) of A/Bar-headed Goose/Qinghai/12/2005. The strongest response has been observed for the long variant with a detection limit of 0.6 pg/mL and a dynamic range from 4.0 to 20.0 pg/mL. The recombinant hemagglutinin (17–527 residues) from A/chicken/Netherlands/1/03 (H7N7), used as the negative control generated a weak response. This confirms the selectivity of the immunsensor proposed. A miniaturized version of the immunosensor, based on screen-printed gold electrodes, was tested with the same set of recombinant hemagglutinins and it achieved a linear range from 1 to 8 pg/mL with a detection limit of 0.9 pg/mL for the long fragment of hemagglutinin.

    ABSTRACT: A non-enzymatic glucose sensor based on a thin layer of nickel immobilized on a gold electrode (EAuNi(OH)2) was used to perform impedimetric determination of glucose. The electrodeposition solution, composed of 0.010 M Ni(NO3)2·6H2O and 1 M of chloride, allows only one active catalyst (NiOOH) to be present on the gold electrode surface after activation with 0.1 M KOH.

    ABSTRACT: A novel electrochemical sensor for gatifloxacin based on one-pot electro-polymerization of β-cyclodextrin (β-CD) and reduced-graphene oxide (rGO) modified glassy carbon electrode (GCE) (β-CD/rGO/GCE) was built for the first time. Scanning electron microscope (SEM) image and Infrared spectroscopy (IR) show that polymer of β-cyclodextrin and reduced graphene oxide (rGO) has been successfully modified on electrode. The electrochemical properties of this polymer were characterized by electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV). The optimization of the electro-polymerized cycle, the pH of supporting electrolyte and the accumulation potential and time were discussed in details. Under optimum conditions, the differential pulse voltammogram (DPV) exhibited the oxidation peak currents were linearly proportional to gatifloxacin concentrations in the range from 0.05 μM to 150 μM with a sensitivity of 0.33 μA μM−1. This electrochemical sensor had a low detection limit of 0.02 μM (S/N = 3). Moreover, this proposed sensor exhibited good reproducibility, long-term stability and fast current response. To further study the practical applicability of the proposed sensor, the modified electrode was successfully applied to detect gatifloxacin in tablets and human urine samples.

    ABSTRACT: In this study, a novel and simple magnetic electrochemical sensing protocol for the sensitive detection of Hg(II) in aqueous media was demonstrated. For this purpose, the halloysite nanotubes-iron oxide–manganese oxide nanocomposite (HNTs-Fe3O4–MnO2) was successfully synthesized for the first time. The synthesis process involves the deposition of Fe3O4 nanoparticles on the surface of HNTs using a simple chemical precipitation method, subsequent formation of wire-like MnO2 nanoparticles on the surface of HNTs-Fe3O4 composites by hydrothermal method with potassium permanganate (KMnO4) and ammonium persulfate ((NH4)2S2O8). The resulting HNTs-Fe3O4–MnO2 nanocomposite was suspended in mercury solution and then brought on the surface of a magnetic carbon paste electrode (MCPE). The amount of analyte was detected electrochemically by applying differential pulse voltammetry (DPV). The conditions of extraction and voltammetric determination were studied and optimized. The proposed method exhibited a linear relationship towards Hg(II) concentrations ranging from 0.5 to 150 μg L−1. The detection limit achieved was 0.2 μg L−1 (3Sb/m), which is lower than the US Environmental Protection Agency (EPA) standard (2 μg L−1 for drinkable water). The proposed methodology was applied for quantification of Hg(II) in real water samples and good recoveries were obtained from 96.0 to 102.7%.

    ABSTRACT: Herein, we developed a novel nanosenor to detect trace amount of melamine (M) in the milk using aptamer-modified surface-enhanced Raman scattering (SERS) nanosensor and oligonucleotide chip. The SERS nanosensor was prepared by attaching Raman tag and ploy-thymine (T) aptamer to the gold nanoparticles, respectively. SERS nanosensor can be absorbed to the oligonucleotide chip with a high specificity where a “T–M–T” structure via multi-hydrogen-bond could be formed between the melamine molecule and the thymine molecule. In the measurement, the Raman signal intensities obtained from the chip increase when the concentrations of melamine in solutions increase. The proposed method allows us to detect melamine with a limit of 1.0 ppt (1.0 pg mL−1), which is fall far below the strictest safety limit. Compared with the previous methods, the sensitivity of this sensor shows about 100-fold improvement. The advantages of the present sensor are its low detection cost and the simplified sample pretreatment. Furthermore, the reliable and enough accurate results have been obtained by the using of the proposed nanosensor in the assay of trace melamine in real milk sample.

    ABSTRACT: We propose a novel method to separate overlapping absorption lines in gas detection based on fiber laser intracavity absorption spectroscopy. The method combines continuous wavelet transform, linear regression analysis and chaos particle swarm optimization together to retrieve the respective absorbance distributions of overlapping lines. The method’s principle is outlined and the rules for parameter selection are given. The performance of the method is demonstrated by both the simulated and experimental data. When the method is applied to the mixed gas concentration calibration of CO and CO2, high linearity is obtained with linear correlation coefficients of 0.9996 and 0.9997 respectively. The relative errors of CO and CO2 concentration retrieval are no more than 0.93% and 1.13% respectively.

    ABSTRACT: A new rhodamine-based derivative bearing pyrrole unit, R1 was synthesized as a dual-mode Cu2+-selective sensor via the rhodamine ring-opening approach and ratiometric displacement. A colorimetric and “off-on” signal for Cu2+ through rhodamine ring opening in R1 and ratiometric fluorescent signal output when Cu2+ displaces the bound Cd2+ in the R1-Cd2+ complex can be observed. The application of fluorescent R1 to biological imaging was also demonstrated.

    ABSTRACT: In this work, a recyclable electrochemical sensing platform to detect breast cancer susceptibility gene (BRCA) was constructed by pillararenes based host–guest recognition and homogeneous DNA hybridization. BRCA target DNA (T-DNA) formed sandwich-type DNA via homogeneous hybridization with methylene blue labeled signal DNA and alkylamino modified capture DNA, which could form complexes with pillararenes. Such sandwich-type DNA was captured by a novel trithiocarbonate modified pillar[5]arene (P5A-CTA) which was immobilized on the Au electrode. With the help of enzyme amplification, the electrochemical detection signal of target DNA in sensing platform was apparently amplified. This sensing platform exhibited wide linear range and excellent specificity, and was particularly recyclable after simple washing with hot acetonitrile due to the reversible host–guest complexation between P5A-CTA and alkylamino modified DNA.

    ABSTRACT: Herein, we report a facile approach to prepare an MWCNT-Fe3O4@PDA-Ag nanocomposite that can act toward purine bases. The nanocomposite was characterized with Fourier-transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FE-SEM), energy-dispersive X-ray spectroscopy (EDS) and transmission electron microscopy (TEM). The characterization results showed that Ag nanoparticles were well anchored onto the polydopamine (PDA) cover of the MWCNT-Fe3O4@PDA nanocomposite. The produced nanocomposite was successfully incorporated as the heart of a sensing element to design a novel electrochemical sensor for individual or simultaneous determination of guanine (G) and adenine (A). The sensor showed an excellent electrocatalytical function toward determination of G and A. The oxidation peak currents were linear over the concentration ranges of 8–130 and 10–120 μM for G and A, respectively. The lower detection limits of the sensor were estimated to be 1.47 μM for G and 5.66 μM for A. The MWCNT-Fe3O4@PDA-Ag nanocomposite based sensor was successfully applied to detect G and A in fish sperm DNA sample.

    ABSTRACT: Nitrogen-doped graphene (NG)-polyvinylpyrrolidone (PVP)/gold nanoparticles (AuNPs) modified screen-printed carbon electrode (SPCE) was prepared for the square wave voltammetric (SWV) determination of hydrazine. For electrode modification, NG-PVP nanocomposites were fabricated on SPCE surface via electrospraying and then AuNPs were electrochemically deposited on top of NG-PVP nanocomposite layer. The factors affecting the sensor sensitivity, such as electrode composition and SWV parameters were optimized. Scanning electron microscopy, transmission electron microscopy, cyclic voltammetry and electrochemical impedance spectroscopy were used for physical and electrochemical characterization of modified electrodes. Due to the synergistic effect of NG-PVP and AuNPs, the modified SPCE showed a 10-time increase in anodic peak current compared with an unmodified SPCE, indicating the high sensitivity of the system. Moreover, this system exhibited an excellent electrocatalytic activity toward hydrazine oxidation. Under optimum conditions, a wide linear range of 2–300 μM, a low detection limit of 0.07 μM and a high sensitivity of 1.370 μA μM−1 cm−2 were obtained for hydrazine. Interestingly, this system was highly selective against a high level of sugars (e.g. glucose, sucrose and lactose). To the best of our knowledge, this is the first report, in which NG-PVP/AuNPs modified SPCE was successfully developed and applied for the detection of hydrazine in high sugar fruit and vegetable samples.

    ABSTRACT: A facile one-step hydrothermal method for a novel discoid crystal of rutile SnO2 modified by reduced graphene oxide (rGO) is reported in this work. X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM) were performed to characterize the structure and morphology of the SnO2/rGO composites. Uniform discoid rutile SnO2 monocrystal with a diameter of approximately 100 nm and a center thickness of 40 nm was anchored on both sides of rGO nanosheets. The SnO2/rGO composite exhibited preferential detection toward NO2 with high response, good selectivity and reproducibility. The response of the sensor to 1 ppm NO2 at 75 °C was nearly one order of magnitude higher than that of SnO2, and the detection limit was improved to 50 ppb. The improved response was discussed and the gas sensing mechanism was established.

    ABSTRACT: In this work, we applied metal-organic frameworks (MOFs) as a porous matrix to encapsulate Cu nanoparticles (NPs) for nonenzymatic glucose sensing in alkaline media. SEM and TEM confirmed that the size of the encapsulated Cu NPs ranges from 2.5 to 5 nm. The hybrid of Cu NPs encapsulated in ZIF-8 (Cu-in-ZIF-8) was further modified onto screen-printed electrodes for nonenzymatic sensing of glucose in alkaline medium. The porous structure of ZIF-8 are beneficial for the unimpeded diffusion of glucose and reaction product. And as a matrix for encapsulating Cu NPs, ZIF-8 also protect the Cu NPs from dissolution and agglomeration during the electrocatalytic process. For comparison, the electrochemical performance of Cu NPs loaded on ZIF-8 (Cu-on-ZIF-8) was also investigated and it is found that Cu-in-ZIF-8 exhibited higher activity and better stability for cyclic test toward the oxidation of glucose in alkaline media. Additionally, Cu-in-ZIF-8 based glucose sensor also shows a favorable sensitivity and selectivity.

    ABSTRACT: A bis-nitrobenzoxadiazole (NBD) derivative of calix[4]arene (L1) and a control compound (L2), mono-NBD derivative of the calixarene were designed and prepared via click chemistry. Fluorescence studies demonstrated that L1 as created can function as a switch with the presence of Ag+ in THF, of which the free state of L1 emits at ∼527 nm, but the binding state at 576 nm. Based upon this discovery, L1 was studied as a chemo-sensor of Ag+ in a mixture solvent of THF and H2O with a detection limit (DL) of ∼6.2 × 10-7 mol/L. Presence of other commonly found metal ions shows little effect upon the determination. Moreover, the L1 in the Ag+-L1 complex could be fully released with introduction of HCHO, a bases for the sensitive and selective detection of the toxic chemical. The DL of this test is 6.6 × 10-7 mol/L. Interestingly, binding and releasing of the fluorescent ligand could be repeated for at least 5 times. Furthermore, both sensing could be performed in a visualized manner. It is believed that the fluorescent compound as created should have a potential to find real-life applications.

    ABSTRACT: In this paper, the Schottky diode sensor composed of silicon nanowires (SiNWs) coated with palladium layers was used for room temperature H2 detection. Pd films were deposited on silicon nanowire via electroless plating. The structural and morphological properties of the Pd/SiNWs were analyzed firstly. The current-voltage (I-V) curves of Pd/SiNWs Schottky diode structure were measured. Variations of the electrical current in the presence of H2 at room temperature revealed that the diode sensors can sense H2 in a wide range of concentration of 300-3000 ppm. This novel sensor has great potential for the detection of H2 at room temperature.
