Magnetic flow cytometry for individual cell detection

摘要

The disclosure relates to flow cytometry. A method for precise individual cell detection and cell measurement of cells in the flow is disclosed. A pair of magnetoresistive components are used to produce a characteristic measuring signal profile from which the following information can be obtained: number of measurement deviations, measurement deviation distances, measurement deviation amplitudes, measurement deviation direction and measurement deviation direction sequence. The flow speed and the cell diameter can also be determined. Also, the signal noise ratio can be determined using the measurement deviation amplitude.
