METHOD AND APPARATUS FOR MAGNETIC FLOW CYTOMETRY

摘要

A magnetic flow cytometry apparatus (1) for detection of cells labeled with magnetic nanoparticles comprising at least one pair of oppositely oriented magnets (2) to provide between said magnets a first magnetic field region (3) with a low magnetic field strength and to provide at poles of said magnets second magnetic field regions (4, 5) with a high magnetic field strength, wherein the magnetic labeled cells (8) provided within a flow input into said magnetic flow cytometry apparatus (1) are enriched in at least one of the second magnetic field regions (4) and supplied to the first magnetic field region (3), where a magnetic field is applied to the enriched magnetic labeled cells (8) to measure the magnetic relaxation of the magnetic labeled cells (8) in response to the applied magnetic field.
