    Amylose of Phragmites Australis captures heavy metals in a box consisting of sugar chains. However, its absorption rate is low in the period of the month scale. Therefore, the electrochemical driving force was used to promote the absorption rate in this research. Amylose was doped with TiO2 porous graphite electrode. The composted absorbent was characterized using XRD(X-ray diffraction), SEM (Scanning Electrode Microscopy), Raman spectroscopy, and electrochemical methods. The affinity and maximum absorption amount were calculated using the isotherm method. In this study, Pb2+, Cu2+, Cd2+, and Cr6+ were chosen to demonstrate because these heavy metals are significant pollutants in Japan’s surface water. It was found that the maximum absorption was Cu2+ (56.82-mg/L) > Pb2+ (55.89-mg/L) > Cr6+ (53.97-mg/L) > Cd2+ (52.83.68-mg/L) at −0.5 V vs. Ag/AgCl. This is approximately the same order as the hydration radius of heavy metals. In other words, the absorption amounts were determined by the size of heavy metal ions. Subsequently, the mixed heavy metal standard solution was tested; the maximum absorption amount was 21.46 ± 10.03 mg/L. It was inferred that the electrochemical driving force could be shown as the ion size effect in the mixed solution. Despite there being no support for this hypothesis at this time, this study succeeded in showing that the electrochemical driving force can improve the ability of the absorbent.

    The zona pellucida (ZP) plays an important role in both the fertilization and embryonic development. For the successful handling of early stage blastomeres for differentiation analysis, the production of identical twins or quadruplets, nuclear transfer or gene introduction requires the removal of the ZP (ZPR). Although single use of either acidic Tyrode's solution or pronase are commonly used for ZPR, long-term exposure to these agents can result in the inhibition of development with the collapse of the three-dimensional blastomere structure. Here, we demonstrate the benefits of using a two-step combined ZPR method, which relies upon a customized well-of-well (cWOW) system with smaller well size, on developmental competence and the quality of the zona free (ZF) mouse embryos. We first isolated 2-cell embryos using acid Tyrode's solution and then cultured these embryos using either commercially available or cWOW, which had a smaller microwell size. The rate of blastocyst was significantly increased by use of cWOW when compared to other culture systems. Then we evaluated the use of a two-step ZPR protocol, relying on acid Tyrode's solution and proteinase K, and subsequent culture in the cWOW system. Although acid Tyrode's solution treatment alone reduced ZPR time, blastomere morphology became wrinkled, significant decrease in blastocyst rate associated with increased number of apoptotic cells and increased expression of apoptosis-related genes were observed. Using proteinase K alone increased ZPR time and significantly decreased the blastocyst rate, but did not induce an increase in apoptotic cell number or apoptosis-related gene expression. In contrast, two-step method significantly reduced ZPR time and improved blastocyst rate by increasing the total number of cells in these wells an reducing the number of apoptotic cells in these experiments. These results suggest that the two-step ZPR protocol is beneficial for reducing the toxic effects of zona removal on ZF embryo development and quality when combined with a suitable culture system.

    A novel two-dimensional organic-inorganic hybrid material containing mouse immunoglobulin G (layered carboxylpropylamidephenylsilica-mouse immunoglobulin G: CPAPhS-mouse IgG) was developed to enhance the sensitivity of the chip used for surface plasmon resonance (SPR). Mouse IgG was covalently attached to the layered CPAPhS using well-established active ester chemistry. CPAPhS-mouse IgG was facilely fabricated onto the Au surface to acquire a novel surface plasmon resonance (SPR) sensor chip, which exhibits higher sensitivity in the detection of the anti-mouse IgG. More interestingly, two different kinds of adsorption equilibrium were exhibited in the unique sensorgram of the anti-mouse IgG, likely due to the unique material structure of the sensor chip.

    The nanostructured thin NiO films with the thicknesses of 30-180 nm were examined as a sensing electrode (SE) for the planar mixed-potential-type yttria-stabilized zirconia (YSZ)-based NO2 sensor. The sensing characteristics were examined in the temperature range of 600-800 °C under the wet condition (5 vol.% water vapor). Among the NiO-SEs tested, the 60 nm-thick NiO-SE sintered at 1,000 °C was found to give the highest NO 2 sensitivity in the NO2 concentration range of 50-400 ppm accompanying with fast response/recovery at the operating temperatures of 600-700 °C. The high NO2 sensitivity was attributed to the high catalytic activity for both electrochemical reactions of O2 and NO2 at the interface of NiO-SE/YSZ. The ultrathin gold layer with the thickness of about 60 nm was additionally formed on the 60 nm-thick NiO-SE to fabricate the laminated-type (60 nm NiO/60 nm Au)-SE. It was demonstrated that the use of this laminated (NiO-Au)-SE improved both the sensitivity and the selectivity to NO2. © 2007 Springer-Verlag.

    We have developed a new immunosensor based on self-assembly chemistry for highly sensitive and label-free detection of 2,4,6-trinitrotoluene (TNT) using surface plasmon resonance (SPR). A monolayer of amine terminated poly(ethylene glycol) hydrazinehydrochloride (PEG-NH2) thiolate was constructed on an activated gold surface and immobilized with trinitrophenyl-beta-alanine (TNPh-beta-alanine) by amide coupling method. The binding interaction of a monoclonal anti-TNT Ab (M-TNT Ab) with TNPh-beta-alanine immobilized thiolate monolayer surface was monitored and evaluated for detection of TNT based on the principle of indirect competitive immunoreaction. Here, the competition between the self-assembled TNT derivative and the TNT in solution for binding with antibody yields in the response signal that is inversely proportional to the concentration of TNT in the linear detection range. With the present immunoassay format, TNT could be detected in the concentration range from 0.008 ng/ml (8 ppt) to 30 ng/ml (30 ppb). The response time for an immunoreaction was 2 min and one immunocycle could be done with in 4 min including surface regeneration. Bound antibodies could be easily eluted from the self-assembled immunosurface at high recoveries (more than 100 cycles) using pepsin solution without any damage to the TNT derivatives immobilized on the surface. The compact self-assembled monolayer was highly stable and prevented the non-specific adsorption of proteins on the surface favoring error free measurement. (c) 2006 Elsevier B.V.

    Highly active and stable electrocatalysts for the reduction of nitrate ions were prepared by the adsorption of PdCl42- ions onto a tin monolayer on Au(111) followed by reduction of the adsorbed PdCl 42-. The maximum atomic ratio of Pd to Sn, and hence the surface Au, determined using a quartz crystal microbalance, X-ray photoelectron spectroscopy and cyclic voltammetry, was 0.87, which corresponds to 0.3 μg-Pd cm-2. Despite such an extremely low loading of Pd, the Pd/Sn/Au electrodes showed high electrocatalytic activity (-3.5 mAcm-2 at -0.1 V vs. Ag|AgCl) and N2 selectivity (37%), both of which are comparable to the highest values reported at different electrodes. In addition, the reduction current on the Pd/Sn/Au electrodes remained constant for hours and decreased only due to the exhaustion of nitrate ions in solution. © 2004 Elsevier B.V.

    Mixed monolayers of ferrocenyloctanethiol (FcC8SH) and alkanethiols of various chain lengths were constructed after predetermining the surface composition by the initial coverage of Pb underpotentially deposited on a bare gold electrode during the first step of the preparation. Single waves observed in the reductive desorption voltammograms show no formation of single-component domains. These mixed monolayers showed the following characteristics. First, a considerable amount of the ferrocene moieties were not electroactive. Second, the mass change during the redox reaction of the ferrocene was greater than that expected from the simple association of the ferrocenium cation with the electrolyte anion, and that for the mixed monolayers prepared from mixed solutions of the precursor thiols. This large mass change was interpreted by the incorporation of the anion and water upon oxidation into the pocket surrounded by alkanethiol and FcC8SH at the bottom. These results are consistent with those expected for the FcC8SH molecules in a domain-free environment, or surrounded by more alkanethiol molecules than FcC8SH molecules. © 2003 Elsevier Science B.V.

    The method we proposed in our previous paper (J. Am. Chem. Soc. 124 (2002) 654) for the construction of mixed monolayers on Au(111) was applied to polycrystalline Au. X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy and reductive desorption voltammetry demonstrate that the surface coverage of mercaptopropionic acid (MPA) in mixed monolayers with alkanethiol was controlled by the initial coverage of Pb underpotentially deposited during the first step of the preparation. In addition, MPA and alkanethiol did not form single-component domains, the sizes of which are large enough to create two distinct sets of reductive desorption waves. In contrast, single-component domains were formed when mixed monolayers were formed from mixed solutions. © 2002 Elsevier Science B.V. All rights reserved.

    Pt/Sn binary metal electrodes were prepared by the successive adsorption of Sn2+ and PtCl62- ions onto a gold substrate followed by the reduction of the adsorbed PtCl62-. The atomic ratios of Sn and Pt to the surface Au were determined to be approximately 1 and 0.3, respectively, using a quartz crystal microbalance (QCM), X-ray photoelectron spectroscopy (XPS) and cyclic voltammetry. Therefore, binary metal layers at a monolayer level were formed. These Pt/Sn binary metal electrodes exhibited a very high electrocatalytic activity for the reduction of nitrate ions with the predominant formation of ammonium ions. © 2002 Elsevier Science B.V.

    Mixed monolayers of 3-mercaptopropionic acid (MPA) and alkanethiols of various chain lengths have been constructed on Au based on a novel concept, namely, control of the composition of the component thiols in mixed monolayers by controlling the surface structure of the substrate. The Au substrate surface was first modified with underpotentially deposited Pb (UPD Pb) atoms, followed by the formation of a self-assembled monolayer (SAM) of alkanethiol. The UPD Pb atoms were then oxidatively stripped from the surface to create vacant site, on which MPA was adsorbed to finally form the mixed monolayers. The surface coverages of Pb, alkanethiol and MPA, and the total numbers of thiols were determined using an electrochemical quartz crystal microbalance, X-ray photoelectron spectroscopy, and reductive desorption voltammetry. These results demonstrate that the surface coverage of MPA in the mixed monolayers is determined by the initial coverage of UPD Pb. Fourier transform infrared spectra also support this conclusion. The observed single peak in the cyclic voltammogram for the reductive desorption shows that MPA and alkanethiol do not form their single-component domains. Scanning tunneling microscopy revealed the single-row pinstripe structure for all the thiol adlayers formed during each step of the preparation. This shows that the surface structure of the mixed monolayers is determined by the structure of the initially formed SAM on Au partially covered with UPD Pb.

    The reductive desorption of self-assembled monolayers (SAMs) of alkanethiols and mercaptoalkanoic acids from gold has been examined in various alkaline solutions and supporting electrolytes using an electrochemical quartz crystal microbalance (EQCM). The desorption exhibits two voltammetric waves: a large dominant wave and another smaller wave at more negative potentials. The appearance of two waves is due to the heterogeneity in the substrate crystallinity and/or in the packing state of the thiol molecules. The desorption charge is calculated after consideration of the charge required to establish the double layer of the uncoated electrode. The mass change per mole of electrons (mpe) for desorption is determined by comparing the frequency change with the total charge passed upon desorption. The mpe increases linearly with the chain length and has a slope close to the mass of CH2, as is expected for a one-electron process. In the case of alkanethiol desorption, however, the mpe is much smaller than the molar mass of the desorbed alkanethiol. This difference is attributed to the simultaneous adsorption of cation species from solution, which is supported by the observed cation dependence of mpe. We estimated the molar mass of the desorbed mercaptoalkanoic acid by summing the mass of this cation species and the mpe for the mercaptoalkanoic acid SAM. From the value thus calculated, we conclude that the terminal carboxylate of the SAM is associated with the solvated cation. The solvation numbers are determined to be 1.6, 2.4-3.0, and 0.2 for Li+, K+, and Cs+, respectively.

    Underpotential deposition(UPD) of Zn2+ ions on polycrystalline platinum in KH2PO4 solution (pH 4.6) was studied by Fourier transform infrared reflection spectroscopy (FTIR) and electrochemical quartz crystal microbalance (EQCM). By the addition of Zn2+ ions in KH2PO4 solution, the intensities of ir bands of around 990, 1044 and 1090 cm-1 are increased with a negative increase of potentials at E ≤ 0.7 V (rhe) where Zn UPD takes place, while by EQCM the weight increase of Pt mounted quartz was observed in the same potential region. Coverage of UPD Zn was 0.75 at 0.05 V as two-electron transfer UPD process, being estimated from cyclic voltammogram, and mps (mass number per platinum sites) was 78 by EQCM from both values the coverage of phosphate was evaluated as 0.27. These results are discussed that the phosphate species adsorbs over UPD Zn on Pt as a form of HPO4, where one of three P - O's seems to be bound to UPD Zn on Pt.

    Detection of 2,4,6-trinitrotoluene (TNT) is an important environmental, security and health concern for the global community. TNT is a prime constituent of most of the landmines and bombs and is highly toxic and mutagenic. Various military and terrorist activities (e.g., manufacturing, waste discharge, testing and training) have resulted in extensive contamination of soil and ground water by TNT and its derivatives. Consequently, the development and application of new sensing techniques for detection and quantification of TNT has grown steadily over the years. Despite wide variety of analytical techniques, surface plasmon resonance (SPR) based immunosensors received great attention as a promising mean for TNT detection due to their advantages including high sensitivity, selectivity, good versatility and high throughput. This review explores the recent trend and advancements in immunochemical techniques for environmental monitoring and field detection of TNT. The advantages of the surface plasmon resonance as an optical signal transduction and indirect competitive immunoassay as the sensing principle are discussed with special emphasis on our investigations on TNT detection. A brief description on explosives, landmines and the current detection techniques (bulk and trace detection) is also provided.

    Recent concern on international terrorism and weapons of mass destruction demands the development of novel analytical methods for identification and quantification of explosive molecules. In this article, we describe the development of high-performance immunosensors for detection of 2,4,6-trinitrotoluene (TNT), a prime component of the landmines and bombs used by terrorist and military forces. The immunosensors were constructed by physical adsorption and self-assembly methods, and their binding interactions with a monoclonal anti-TNT antibody were evaluated for TNT detection using the surface plasmon resonance technique. A home-made 2,4,6-trinitrophenyl-keyhole limpet hemocyanine conjugate was used for physical adsorption. A poly( ethylene glycol) hydrazine hydrochloride thiolate was used in the construction of self-assembled monolayer surface and was immobilized with trinitrophenyl- beta-alanine by the amide coupling method. The immunosensors were highly selective, regenerable, rapid, and exhibited remarkable sensitivity down to the parts-per-trillion level for TNT by the indirect competitive inhibition principle.

    Detection of TNT is an important environmental and security concern all over the world. We herein report the performance and comparison of four immunoassays for rapid and label-free detection of 2,4,6-trinitrotoluene (TNT) based on surface plasmon resonance (SPR). The immunosensor surface was constructed by immobilization of a home-made 2,4,6-trinitrophenyl-keyhole limpet hemocyanin (TNPh-KLH) conjugate onto an SPR gold surface by simple physical adsorption within 10 min. The immunoreaction of the TNPh-KLH conjugate with four different antibodies, namely, monoclonal anti-TNT antibody (M-TNT Ab), monoclonal anti-trinitrophenol antibody (M-TNP Ab), polyclonal anti-trinitrophenyl antibody (P-TNPh Ab), and polyclonal anti-TNP antibody (P-TNP Ab), was studied by SPR. The principle of indirect competitive immunoreaction was employed for quantification of TNT. Among the four antibodies, the P-TNPh Ab prepared by our group showed highest sensitivity with a detection limit of 0.002 ng/mL (2 ppt) TNT. The lowest detection limits observed with other commercial antibodies were 0.008 ng/mL (8 ppt), 0.25 ng/mL (250 ppt), and 40 ng/mL (ppb) for M-TNT Ab, P-TNP Ab, and M-TNP Ab, respectively, in the similar assay format. The concentration of the conjugate and the antibodies were optimized for use in the immunoassay. The response time for an immunoreaction was 36 s and a single immunocycle could be done within 2 min, including the sensor surface regeneration using pepsin solution. In addition to the quantification of TNT, all immunoassays were evaluated for robustness and cross-reactivity towards several TNT analogs.
