Document Type and Number:
WIPO Patent Application WO/2005/085853
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a biochip that realizes securely immobilizing of chemical substances on a substrate in a liquid without deterioration to the activity thereof and further realizes detecting of any interaction between one or two or more chemical substances immobilized on the substrate and an analyte in a liquid. [MEANS FOR SOLVING PROBLEMS] Use is made of a biochip characterized in that two or more chemical substance binding carriers respectively having different chemical substances bound thereto have been immobilized on a substrate in a liquid. Further, use is made of a method of detecting any interaction between analyte and chemical substance in a liquid by means of the above biochip, comprising the step of bringing an analyte into contact with a substrate having chemical substance binding carriers immobilized thereon and the step of detecting any interaction within a given zone of the substrate only.
