    摘要: A gas phase species (such as ozone, H2O2, or N2O) is photodissociated with ultraviolet light into a reactive species that is patternwise directed (e.g., through a mask) onto a surface of a material, such as an organosilicate. The reactive species reacts with the material to form a polar oxidation product such as —OH, thereby resulting in discrete hydrophilic regions separated from each other by hydrophobic regions. The degree of hydrophilicity of the discrete regions may be tailored by controlling the concentration of the reactive species, the ultraviolet light intensity, the temperature to which the material is heated, and exposure time. End products made with the methods are suitable for use in a biomolecular array.

    摘要: Nanoparticles in a colloid are purified, with the colloid including a fluid, unwanted matter, and the nanoparticles to be purified. An electric field is applied that is substantially spatially uniform over a distance that is at least equal to a characteristic dimension of the nanoparticles, so that at least some of the nanoparticles move towards at least one collection surface as a result of the force arising between their electrical charge and the electric field, whereupon nanoparticles are collected on said at least one collection surface. The collection surface(s) may be one or more electrodes to which a voltage potential is applied. The collected nanoparticles are then removed from the collection surface, e.g., by dispersing them into another fluid.

    摘要: Nanoporous structures are constructed that have hydrophilic regions separated by hydrophobic regions. The porous, hydrophilic regions have reaction sites suitable for use in a bioassay application and have a higher density of reaction sites than that of a non-porous (2-D) surface. The structure may be made by depositing a layer of a matrix material (e.g., an organosilicate) and a porogen, and then crosslinking the matrix material to form a nanohybrid composite structure. The porogen is decomposed to form pores within the matrix material, and a reactive gas phase species (e.g., ozone) is patternwise directed onto a surface of the matrix material. Ultraviolet light (directed through a mask) activates the gas phase species to form a reactive species that then reacts with the matrix material to make it hydrophilic. The porogen may be decomposed thermally or by exposing it to an oxidizing atmosphere in the presence of ultraviolet light.

    摘要: A first nanoscale self-aligned self-assembled nested line structure having a sublithographic width and a sublithographic spacing and running along a first direction is formed from first self-assembling block copolymers within a first layer. The first layer is filled with a filler material and a second layer is deposited above the first layer containing the first nanoscale nested line structure. A second nanoscale self-aligned self-assembled nested line structure having a sublithographic width and a sublithographic spacing and running in a second direction is formed from second self-assembling block copolymers within the second layer. The composite pattern of the first nanoscale nested line structure and the second nanoscale nested line structure is transferred into an underlayer beneath the first layer to form an array of structures containing periodicity in two directions.

    摘要: A layered structure comprising a self-assembled material is formed by a method that includes forming a photochemically, thermally and/or chemically treated patterned photoresist layer disposed on a first surface of a substrate. The treated patterned photoresist layer comprises a non-crosslinked treated photoresist. An orientation control material is cast on the treated patterned photoresist layer, forming a layer containing orientation control material bound to a second surface of the substrate. The treated photoresist and, optionally, any non-bound orientation control material are removed by a development process, resulting in a pre-pattern for self-assembly. A material capable of self-assembly is cast on the pre-pattern. The casted material is allowed to self-assemble with optional heating and/or annealing to produce the layered structure.

    摘要: A method for producing surface features and an etch masking method. A combination is provided of a block copolymer and additional material. The block copolymer includes a first block of a first polymer covalently bonded to a second block of a second polymer. The additional material is miscible with the first polymer. A film is formed of the combination directly onto a surface of a first layer. Nanostructures of the additional material self-assemble within the first polymer block. The film of the combination and the first layer are etched. The nanostructures have an etch rate lower than an etch rate of the block copolymer and lower than an etch rate of the first layer. The film is removed and features remain on the surface of the first layer. Also included is an etch masking method where the nanostructures mask portions of the first layer from said etchant.
