    • Chemical and biosensors are disclosed. An optical waveguide is used to conduct electromagnetic radiation by total internal reflection in parallel through a reference waveguide portion and at least one analyte waveguide portion. The electromagnetic radiation is then converged into an exit beam. The external surface of at least the analyte portion is covalently modified, or functionalized, relative to the reference portion. Resulting interaction of the functionalized surface with molecules comprising an analyte causes a phase change in the electromagnetic radiation passing through the analyte portion relative to the reference portion sufficient to generate a corresponding and measurable interference pattern in the exit beam. A waveguide surface is functionalized by exposure to a reagent, having molecules each comprising a nitrenogenic group and a functionalizing group, in the presence of energized charged particles such as electrons and ions, photons, or heat, which transform the nitrenogenic reagent to a nitrene intermediate. The resulting reaction causes the functionalizing groups to covalently bond to the surface. The functionalizing groups can then participate in downstream chemistry whereby any of a large variety of functional groups, including biological molecules, can be covalently bonded to the surface. Thus, the waveguide surface can be made selectively responsive to a wide variety of analytes, including cells and other biological structures.
    • 公开了化学和生物传感器。 光波导用于通过参考波导部分和至少一个分析物波导部分并行地通过全内反射来传导电磁辐射。 电磁辐射然后会聚到出射光束中。 至少分析物部分的外表面相对于参考部分共价修饰或官能化。 功能化表面与包含分析物的分子的相互作用导致相对于参考部分通过分析物部分的电磁辐射的相变足以在出射光束中产生相应和可测量的干涉图案。 波导表面通过暴露于具有各自包含硝基衍生基团和官能化基团的分子的试剂而被功能化,所述分子在有电的带电粒子例如电子和离子,光子或热的情况下,其将硝化反应试剂转变为硝酸中间体 。 所得到的反应使官能团共价键合到表面。 官能团然后可以参与下游化学,因此包括生物分子在内的各种各样的官能团中的任何一个可以共价键合到表面上。 因此,波导表面可以选择性地响应于各种各样的分析物,包括细胞和其他生物结构。

    • A molecularly imprinted substrate and sensors employing the imprinted substrate for detecting the presence or absence of analytes are described. One embodiment of the invention comprises first forming a solution comprising a solvent and (a) a polymeric material capable of undergoing an addition reaction with a nitrene, (b) a crosslinking agent (c) a functionalizing monomer and (d) an imprinting molecule. A silicon wafer is spincoated with the solution. The solvent is evaporated to form a film on the silicon wafer. The film is exposed to an energy source to crosslink the substrate, and the imprinting molecule is then extracted from the film. The invention can be used to detect an analyte by forming films which are then exposed to a reaction energy to form a crosslinked substrate. The imprinting molecules are extracted from the crosslinked substrate. The film is exposed to one or more of the imprinting molecules for a period of time sufficient to couple the imprinting molecules to the film. The presence of the molecules is then detected. The invention also provides a molecularly imprinted polymeric material and sensors employing the molecularly imprinted polymeric material.

    • A method for forming arrays of metal, alloy, semiconductor or magnetic clusters is described. The method comprises placing a scaffold on a substrate, the scaffold comprising molecules selected from the group consisting of polynucleotides, polypeptides, and perhaps combinations thereof. Polypeptides capable of forming α helices are currently preferred for forming scaffolds. Arrays are then formed by contacting the scaffold with plural, monodispersed ligand-stabilized clusters. Each cluster, prior to contacting the scaffold, includes plural exchangeable ligands bonded thereto. If the clusters are metal clusters, then the metal preferably is selected from the group consisting of Ag, Au, Pt, Pd and mixtures thereof. A currently preferred metal is gold, and a currently preferred metal cluster is Au55 having a radius of from about 0.7 to about 1 nm. Compositions also are described, one use for which is in the formation of cluster arrays. One embodiment of the composition comprises plural monodispersed, ligand-stabilized clusters coupled to a polypeptide.
