発明の名称 (英語) TARGET ANALYSIS METHOD AND TARGET ANALYSIS CHIP NEW
発明の概要(英語) Provided are a novel target analysis method and target analysis chip for directly detecting targets such as micro-RNA without performing PCR. This target analysis method is characterized in comprising: a step for bringing a target in a sample, a labelling probe for binding to the target, and a carrier-binding probe for binding to the target and a carrier into contact to cause a binding reaction between the target, the labelling probe and the carrier-binding probe and form a first complex; a step for bringing the first complex into contact with the carrier to cause a binding reaction between the first complex and the carrier and form a second complex; a step for concentrating the carrier; and a step for analyzing the target in the sample by detecting the labelling of the labelling probe that is bound to the concentrated carrier.
