摘要:
A particle having a large amount of biosubstances per unit volume has been needed for application to biosensors and the like. Accordingly, the present invention provides the particle comprising mesopores in which biosubstances are held and having a diameter ten times or less as large as the diameter of the mesopores.
摘要:
An excellent mesostructured thin film, and a process for producing the mesostructured thin film are provided. In the process, the mesostructured thin film having an oriented rod-like pore structure is formed on a surface of a polymer compound containing a sequence of two or more adjacent methylene groups in the repeating unit of the molecule.
摘要:
In order to provide an FET biosensor which enables the highly sensitive detection, the present invention employs a field-effect transistor comprising a source region, a drain region and a gate region, wherein the gate region employs a porous material having mesopores of which the walls contain crystals of tin oxide.
摘要:
A process for producing a pigment complex including the steps of dissolving a pigment in a supercritical state or subcritical state fluid and contacting the fluid containing the dissolved pigment with a polymer-containing solution.

A thermoelectric conversion material and a thermoelectric conversion device having a novel structure of an increased figure of merit are provided by forming nano-wires of thermoelectric material in a smaller cross-sectional size. The thermoelectric conversion material comprises nano-wires obtained by introducing a thermoelectric material (semiconductor material) into columnar pores of a porous body. The porous body is formed by providing a structure in which columns of a column-forming material containing a first component (for example, aluminum) are distributed in a matrix containing a second component (for example, silicon or germanium or a mixture of them) being eutectic with the first component, and then removing the column-forming material from the structure. The average diameter of the nano-wires of the thermoelectric material is 0.5 nm or more and less than 15 nm, and the spacing of the nano-wires is 5 nm or more and less than 20 nm.
摘要:
A method of forming, on a substrate, minute-sized columnar portions of a columnar structured material at minute intervals, and a columnar structured material formed by the manufacturing method. A columnar structured material is formed through an etching process in which a pattern of minute dots formed on the substrate is utilized as a mask. The pattern of the minute dots is obtained by introducing a mask material into columnar microholes of a porous film formed on the substrate and then removing the porous film. The porous film is formed by removing columnar substances from a structured material in which the columnar substances which are so formed as to contain a first component are dispersed in a matrix which is made of another component and is so formed as to contain a second component that can form a eutectic together with the first component.
