Claim Text:
1. A device for magnetophoretic analyte selection and enrichment, the device comprising: a flow channel having a first section, a second section, and a third section, wherein the second section is positioned between and adjacent to the first section and the third section such that the second section links the first section and the third section, and wherein the flow channel splits into at least a first part-channel and a second part-channel in the second section of the flow channel; a first magnetic unit arranged in the first section of the flow channel, wherein the first magnetic unit produces a magnetic gradient field that enriches magnetically marked analytes within the flow channel at a bottom of the flow channel; and a second magnetic unit arranged in the first section of the flow channel, wherein the second magnetic unit aligns the magnetically marked analytes within the flow channel along an axis that continues in the first part-channel of the third section, such that the first part-channel in the third section and the flow channel in the first section extend along the same axis, and wherein the first part-channel in the third section of the flow channel has a cross-sectional area that is smaller than a cross-sectional area of the flow channel in the first portion.
