Claim:
1. An apparatus for flow cytometry, the apparatus comprising: a flow channel; a magnetic unit that is arranged below a channel bottom of the flow channel and is configured to generate a gradient magnetic field that permeates a volume enclosed by the flow channel; at least one cell measuring device; and at least one guide step that is arranged in the flow channel such that cells that are flowable through the flow channel are deflectable toward the at least one cell measuring device by the at least one guide step, wherein the at least one cell measuring device is arranged on or in the channel bottom, wherein the at least one guide step comprises a plurality of guide steps that are arranged in the flow channel such that the cells that are flowable through the flow channel are enrichable by the plurality of guide steps in a subvolume of the flow channel over a subsurface of the channel bottom, and wherein the plurality of guide steps extend away from the channel bottom of the flow channel such that the plurality of guide steps are barriers that exert mechanical forces on the cells that are flowable through the flow channel and a subset of the cells that are flowable through the flow channel do not flow over the plurality of guide steps.
