摘要:
A liquid containing a separation target substance is brought into contact with a double helix DNA-holding phase to have the separation target substance held by the double helix DNA-holding phase, which is then removed from the liquid. On this occasion, the contact of the double helix DNA with the separation target substance is performed in an aqueous medium having a salt concentration of 0.02 mass % or more.

Provided are a DNA carrier where DNA is firmly held in a substrate, which can reduce the elution of DNA into water and can take full advantage of the capability of DNA to selectively and specifically collect a substance; and a method of producing the DNA carrier. Also provided is a collection system using DNA, which can be used in the high-accuracy detection of a particular substance and in an environmental cleanup capable of efficiently removing a substance, in which the DNA carrier is used to collect the substance contained in air or water by taking full advantage of the capability of DNA to selectively and specifically collect the substance. The DNA carrier is one where DNA is held in a porous matrix containing polyorganosiloxane with a basic functional group and particles. Preferably, the polyorganosiloxane with a basic functional group contains a hydrolysis condensate of one or more of particular silane compounds with an amino group.

There is provided a DNA supporting fiber capable of maintaining the stability of DNA and efficiently expressing the adsorption property of DNA. Also provided is a DNA supporting sheet useful in a variety of applications, the sheet that utilizes the fiber. The DNA supporting fiber is produced by fusing and fixing, onto the surface composed of a thermoplastic resin of a fiber, particles where DNA as an adsorbent is immobilized in a porous matrix containing an inorganic oxide.
摘要:
Provided is a structure designed for adsorption, which is suitable for removing dioxin and dioxin-like substances from leachate and ground water from polluted soils or garbage, washing effluent from garbage incinerators and so on that contain DNA intercalators, particularly, dioxin and dioxin-like substances. The structure designed for adsorption is a structure designed for adsorption having an adsorbing layer containing, as a constituent, a DNA complex containing a DNA-binding protein, DNA including double strand DNA and a carrier, which can selectively remove DNA intercalators with high efficiency from water, gas and so on containing them.

摘要:
The membrane electrode assembly of the present invention for the proton-exchange membrane fuel cell includes a polymer electrolyte membrane and an electrode catalyst layer, wherein at least a part of the polymer electrolyte membrane infiltrates into the electrode catalyst layer, and wherein the polymer electrolyte membrane is formed by polymerizing a composition containing at least a compound having proton conductivity and a compound having activity to an active energy ray, or a composition containing at least a compound having proton conductivity and activity to the active energy ray. The object of the present invention is to provide a membrane electrolyte assembly for realizing a high-output proton-exchange membrane fuel cell by improving a bonding state between the polymer electrolyte membrane and the electrode catalyst layer to reduce an internal resistance, and by providing a three-dimensional three-phase interface to increase reaction areas.
