Abstract

A magnetic particle manipulation method for magnetic particle comprises the steps of; subjecting magnetic particles and a magnetic solid having a larger particle diameter than said magnetic particles to existing together in a liquid layer, and moving said magnetic solid and said magnetic particles in said liquid layer by a magnetic field manipulation. According to one aspect of the present invention; a manipulation method for magnetic particles comprising the steps of; moving magnetic particles in a first liquid layer into a gelled medium layer by a magnetic field manipulation in a device, wherein gelled medium layers and liquid layers are in-place alternately in a container, moving said magnetic particles present in the gelled medium into a second liquid layer by the magnetic field manipulation; and moving said magnetic particles along with said magnetic solid in the second liquid layer.
