    摘要:
    一系列密切相关的寡聚(乙二醇)末端链烷硫醇酰胺(主要是HS(CH(2))(m)CONH(CH(2)CH(2)O)(n)H; m的合成策略= 2、5、11、15,n = 1、2、4、6、8、10、12),并且已经开发出类似的酯。制备这些化合物是为了研究金上自组装单分子膜(SAMs)的结构和稳定性,以期设计出新的生物传感界面。为此,制备了具有多达12个单元的单分散性杂官能低聚(乙二醇)。使用氧化银(I)对对称的四和六(乙二醇)二醇作为甲磺酸酯进行选择性单酰化。合成方法基于各种低聚(乙二醇)衍生物的碳二亚胺通过末端氨基或羟基官能团与ω-(乙酰硫基)羧酸的偶联。研究了金的SAM结构的厚度,润湿性(水接触角约为30度)和构象。对于单层厚度(d)与低聚(乙二醇)链中单元数(n)之间的关系,获得了很好的拟合:d = 2.8n + 21.8(A)。有趣的是,相应的红外光谱分析表明寡聚链的构象从全反式(n =

    Multiple Electron Tunneling Paths across Self-Assembled Monolayers of Alkanethiols with Attached Ruthenium(II/III) Redox Centers
    摘要:
    Alkanethiol monolayers with pendant redox centers are deposited on gold electrolytes by self-assembly. The monolayers are composed of both an electroactive thiol, HS(CH2)(n)C(O)NHCH(2)pyRu(NH3)(5)(2+/3+), with 10-15 methylene groups, and a diluent thiol, HS(CH2)mCoOH, also with 10-15 methylene groups. The monolayers are classified as ''matched'' (n = m), ''exposed'' (n = 15, m = 10-14), and ''buried'' (n = 10, m = 11-15) according to the relative position of the redox center. Cyclic voltammograms in aqueous Na2SO4 indicate that the monolayers are close-packed with the redox centers residing in the aqueous phase in all but the most buried cases. Measurements of electron transfer kinetics by several methods (cyclic voltammetry, ac impedance spectroscopy, chronoamperometry) yield an internally consistent set of kinetic parameters, the standard rate constant k degrees, and the reorganization energy lambda of the redox centers. The reorganization energies are in good agreement with the theoretically predicted value of 1.0 eV for the pyRu(NH3)(5) redox centers. Plots of ln(k degrees) vs m are linear in all three cases. The slopes of the linear regression fit provide tunneling parameters (beta, where k degrees approximate to e(-beta m)) of 0.97 +/- 0.03 (matched cases), 0.83 +/- 0.03 (exposed cases) and 0.16 +/- 0.02 (buried cases) per methylene. This pattern of beta's is interpreted in terms of electronic coupling between the redox center and the electrode via both the redox thiol and the proximate diluent thiols, with the coupling via the diluent thiols dominating in the exposed cases.

  • High-Affinity Chelator Thiols for Switchable and Oriented Immobilization of Histidine-Tagged Proteins: A Generic Platform for Protein Chip Technologies

    dissociation, drastically improved stability of protein binding by these multivalent chelator surfaces was observed. The immobilized histidine-tagged proteins are uniformly oriented and retain their function. At the same time, proteins can be removed from the chip surface under mild conditions (switchability). This new platform for switchable and oriented immobilization should assist proteome-wide wide analyses
    在探索蛋白质-蛋白质相互作用和动态蛋白质网络的系统方法中,蛋白质微/纳米阵列正变得越来越重要,因此,对将特定的,通用的,稳定的,均匀的和局部可寻址的蛋白质固定在固体支持物上的需求很高。在这里,我们介绍了多价金属螯合硫醇,适用于组氨酸标记的蛋白质在生物相容性自组装单分子膜(SAMs)上的稳定结合。这些SAM的结构和理化性质已通过各种表面敏感技术进行了探索,例如接触角测角法,椭圆偏振法和红外反射吸收光谱法。通过表面等离振子共振,共聚焦激光扫描和原子力显微镜证实了蛋白质和蛋白质复合物的特定分子组织。与由于其低亲和力和快速解离而具有主要缺点的mono-NTA / His6标签相互作用相反,观察到这些多价螯合剂表面显着改善了蛋白质结合的稳定性。固定化组氨酸标签的蛋白质均一地定向并保持其功能。同时,蛋白质可以在温和的条件下(可切换性)从芯片表面去除。这个用于可切换和定向固定的新平台应有助于蛋白质组间广

    日期:——
    An oligonucleotide modified with Ni-nitrilotriacetate (NTA) was successfully synthesized and used for the stoichiometric functionalization of QDs. This synthetic approach allowed for the facile preparation of DNA–QD conjugates with a defined DNA/QD ratio using well-known Ni–histidine coordination chemistry. A FRET based DNA–QD nanoprobe was prepared using this method highlighting the great potential of this synthetic strategy.
