    ABSTRACT: Quantum dot sensitized photoanodes have drawn much attention due to their high potential as efficient anodes for photoelectrochemical (PEC) water splitting or solar cells. However the photocorrosion of QDs is the crucial barrier for applications in these devices. The in situ analysis of photocorrosion is important in understanding its mechanism and also developing the possible solution for photocorrosion. In this study we have developed a novel, integrated analysis system for in situ measurements of photocorrosion and PEC performances. We have fabricated the CdSe/CdS/ZnO nanowire (NW) arrays on quartz crystal microbalance (QCM) as a platform for usage as PEC photoanodes and also mass analysis at the same time. The in situ measuring of photocurrents and mass changes were performed with continuous operation of PEC cells for CdSe/CdS/ZnO NWs photoanode. The study exhibited highly correlated tendency in photocurrent decrease and mass reduction, due to photocorrosion of CdSe/CdS/ZnO NWs. Also to improve the photostability of CdSe/CdS/ZnO NWs, applications of passivation and catalysts were studied and their effects were discussed. Our integrated in situ analysis system is highly applicable to various semiconductor sensitized systems.

    ABSTRACT: N6-methyladenosine (m6A) is a ubiquitous modification in mRNA and other RNAs across most eukaryotes, which is likely dynamically regulated throughout developmental processes. In this work, an electrochemical immunosensor was fabricated for RNA methylation detection using gold nanoparticles modified glassy carbon electrode (AuNPs/GCE) as substrate electrode. The assembly of 4-aminophenylboronic acid on AuNPs/GCE triggered the further immobilization of anti-m6A antibody on the substrate electrode through the specific interaction between boric acid and glycosyl of antibody, which led to the following capture of methylated RNA through the immunoreaction. A decreased electrochemical reduction signal of the redox probe of [Fe(CN)6]3− was obtained based on the synergistic effect of electrostatic repulsion and steric hindrance. The developed method showed a wide linear range for methylated RNA from 0.01 to 10 nM and the detection limit was 2.57 pM (S/N = 3). Moreover, the down-regulated expression of methylation level of mRNA in the leaves of rice seedlings after incubation with 6-benzylaminopurine was confirmed by the fabricated biosensor, indicating the great potential for assaying the expression level of methylated RNA in real sample.

    ABSTRACT: Recombination of electrolysis gases (oxidation of hydrogen and reduction of oxygen) is an important factor in operation efficiency of devices employing electrolysis such as actuators and also unitized regenerative fuel cells. Several methods of improving recombination speed and repeatability were developed for application to electrolysis microactuators with Nafion®-coated catalytic electrodes. Decreasing the electrolysis chamber volume increased the speed, consistency, and repeatability of the gas recombination rate. To further improve recombination performance, methods to increase the catalyst surface area, hydrophobicity, and availability were developed and evaluated. Of these, including in the electrolyte pyrolyzed-Nafion®-coated Pt segments contained in the actuator chamber accelerated recombination by increasing the catalyst surface area and decreasing the gas transport diffusion path. This approach also reduced variability in recombination encountered under varying actuator orientation (resulting in differing catalyst/gas bubble proximity) and increased the rate of recombination by 2.3 times across all actuator orientations. Repeatability of complete recombination for different generated gas volumes was studied through cycling.

    ABSTRACT: The demand for advanced, sensitive, and low-cost sensor platforms is growing. However, sensors containing biological recognition elements sometimes present restrictions, which limit their use. This work focused on the development of surface plasmon resonance (SPR) based on a molecularly imprinted polymer (MIP) film, which builds a foundation for biomimetic sensors. The MIP films in the sensor chip were prepared by spin-coating method. The MIP film was found to be readily incorporated into the sensor for detection of histamine in aqueous media. The effect of pH conditions was also investigated. The sensing technique allows for the detection of histamine in a wide range of concentration from 25 μg L−1 to 1000 μg L−1. By using structural analogs, the sensor platform was demonstrated to be specific for the detection of histamine.

    ABSTRACT: SnO2–ZnO hetero-nanofibers were fabricated by a facile electrospinning method and calcination in this study. The SnO2–ZnO nanofibers were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), Brunauer–Emmett–Teller (BET) and X-ray diffraction (XRD). The gas sensor prepared by the SnO2–ZnO hetero-nanofibers revealed better ethanol sensing performance than pure ZnO and pure SnO2 nanofibers, good stability and excellent selectivity at the optimum temperature of 300 °C. The response and recovery time to 100 ppm ethanol were about 25 s and 9 s, respectively. The growth mechanism of the hetero-nanofibers was discussed, as well as the ethanol adsorption–desorption mechanism.

    ABSTRACT: A dual carcinoembryonic antigen (CEA) biosensing alternative optoelectric platforms has been developed based on gold modified ITO electrode. The new platform is constructed by assembly of a thiol-derivative-nanogold (TDN) labeled anti-CEA (TDN-anti-CEA) antibody on a gold/indium tin oxide (ITO) electrode to create a high CEA sensitive surface. The gold film deposited on ITO glass provides a desirable substrate for the immobilization of the TDN-anti-CEA antibody and improves the compatibility between nanogold and electrode which results in a significant amplification. By using the same TDN-anti-CEA antibody probe, the CEA (analyte) was analyzed using two different methods; electrochemical impedance spectroscopy (EIS) and ultraviolet (UV) spectroscopy, the results showed that the limit of detection was 1 and 2 pg/ml by EIS and UV methods, respectively. Given their promising advantages, it is likely that dual platforms will evolve to be an attractive tool for use in many different fields.

    ABSTRACT: A rapid, facile fluorescence sensing strategy was developed for dopamine (DA) detection based on polydopamine (pDA) formed on the surface of graphene quantum dots (GQDs). The prepared GQDs were strongly luminescent because of the aromatic planar structure. DA could self-polymerize to pDA and snap to the surface of GQDs to form a thin film in alkaline environment, leading to quenching of fluorescence due to fluorescence resonance energy transfer (FRET). With the optimized conditions, the analytical performance illustrated high sensitivity, selectivity in a wide linear range with a detection limit of 8 nM. In addition, the unique method was successfully applied for DA injection test with satisfactory labeled amount. Finally, the proposed strategy was applied for DA detection in serum, wherein accurate results were obtained.

    ABSTRACT: We describe an inexpensive paper-based sensor for rapid detection of low concentrations (ppm) of hydrogen cyanide gas. A piece of filter paper pre-spotted with a dilute monocyanocobinamide [CN(H2O)Cbi] solution was placed on the end of a bifurcated optical fiber and the reflectance spectrum of the CN(H2O)Cbi was monitored during exposure to 1.0-10.0 ppm hydrogen cyanide gas. Formation of dicyanocobinamide yielded a peak at 583 nm with a simultaneous decrease in reflectance from 450-500 nm. Spectral changes were monitored as a function of time at several relative humidity values: 25, 50, and 85% relative humidity. With either cellulose or glass fiber papers, spectral changes occurred within 10 s of exposure to 5.0 ppm hydrogen cyanide gas (NIOSH recommended short-term exposure limit). We conclude that this sensor could provide a real-time end-of-service-life alert to a respirator user.

    ABSTRACT: Biochanin A (BnA) a natural o-methylated isoflavone, is isolated from the leaves of Eupatorium adenaphorum and is effectively utilized as a sensor probe for copper ion with good selectivity and sensitivity. The effect with the presence of other metal ions is also investigated and BnA is found to be selective towards Cu2+ ion over other metal ions such as Zn2+, Sn2+, Ni2+, Ag+, Bi2+, Pb2+, Co3+, In3+, Mn2+, Fe2+, Li+, Hg2+ and Ca2+ at pH 7.1 with a detection limit upto 1.0 × 10−6 mol L−1. The sensor probe BnA exhibits selective fluorescence quenching via an intramolecular charge transfer (ICT) upon addition of Cu2+. The proposed mechanism is strongly supported by TD-DFT calculations and the 1:1 complex (BnA–Cu2+) formation is confirmed by ESI-MS and Job's plot.

    ABSTRACT: A rarely reported polymorphic lanthanide complex is prepared by acetylacetone (acac) tuning method. Luminescence properties of 1 are studied. Interestingly, 1 is proved to be a multifunctional material. It is a highly selective and sensitive Co2+ sensor, among 24 species, only Co2+ quenching the Tb3+ centered luminescence. The possible sensing mechanism is the decomposition of 1 which induced by Co2+. The limit of detection (LOD) for sensing Co2+ is as low as 330 nM, which is lower than the standard of Chinese environmental protection department. Mechanism study confirmed the luminescence quenching can be ascribed to the decomposition of 1 which induced by Co2+. Further investigations find 1-Co2+ can be applied as tunable luminescent timer, by tuning the ratio of 1/Co2+. CIE coordinates of 1-Co2+ change regularly (has excellent linearity) from green to violet with the time increasing.

    ABSTRACT: This work describes the design and fabrication of a novel multianalyte biosensor platform for medical diagnostic applications. The sensor platform consists of a photonic waveguide-based optical circuit used to deliver excitation light to multiple sensor windows on the platform. The platform is fabricated by UV-photopatterning of photocurable hybrid organic–inorganic sol–gel materials. The sensing mechanism is based upon the detection of fluorescently labelled antibodies, in order to determine the concentration of specific analytes in a test solution. Fluorescence is excited by means of the evanescent wave in each sensor window. It is shown that the sensing properties of the platform can be dramatically enhanced by increasing the intensity of the evanescent field of the light propagating in the optical waveguide by a precise design of a high refractive index layer deposited at the waveguide surface. This work proved the concept of employing a waveguide-based photonic platform for the detection of fluorescently labelled antibodies, with μg/ml detection levels, and as such, we believe this system has immense potential for future applications as a medical diagnostic platform.
