Abstract
A chip device for manipulating an object component is described, in which multiple liquid substances such as reagents required for a series of manipulations on a sample are stably secured in separated states throughout the manipulations within the device. The chip device includes a manipulation chip, magnetic particles, and a magnetic field application means. The manipulation chip includes a substrate, a groove formed in the surface of the substrate, and a manipulation medium accommodated in the groove such that gel phases and aqueous liquid phases are alternately disposed in the longitudinal direction of the groove and are in contact with each other. The magnetic particles are for capturing and carrying the object component. The magnetic field application means is capable of moving the magnetic particles in the longitudinal direction of the groove in the substrate by the application of a magnetic field to the substrate.
