摘要： Silicon grids with electron-transparent SiO2 windows for use as substrates for high-resolution transmission electron microscopy of chemically-modified SiO2 surfaces are fabricated by forming an oxide layer on a silicon substrate. An aperture is defined in the silicon substrate by etching the substrate to the oxide layer. A single substrate can include a plurality of apertures that are in respective frame regions that are defined by one or more channels in the substrate. Tabs are provided to secure the frame regions to the substrate, and the tabs are readily broken to obtain a particular frame region. Conductive or other features can be defined on the oxide layers prior to separation of the frame regions from the substrate.

摘要： 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.

摘要： Methods for selectively depositing nanostructures on a support layer include contacting the support layer with functionalized catalyst particles. The functionalized catalyst particles can form a self-assembled monolayer of catalyst particles on the support layer and the functionalized catalyst particles can be used to catalyze nanostructure growth. In one embodiment of the disclosed method, zinc oxide nanowires are grown on a patterned substrate using functionalized gold nanoparticles. Patterned arrays of self-assembled nanostructures and nanoscale devices using such nanostructure arrays are also described.
