  • Publication number: 20080176227
    Abstract: 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.
