AI Technical Summary
The magnetic particles in the droplets are irregularly distributed in the magnetic field, resulting in less obvious peaks in fluorescence signal characteristics, affecting cell recognition accuracy.
The pre-magnetization assembly is used to generate a pre-magnetization magnetic field, so that the magnetic particles are agglomerated in the liquid droplets, and then a first magnetic field is formed through the magnet assembly, so that the agglomerated magnetic particles are pulled into a linear shape in the first magnetic field, enhancing the fluorescence signal.
By combining pre-magnetization and the first magnetic field, the identification accuracy of the droplets is improved, making the characteristic peaks of the fluorescence signal more obvious and reducing misjudgment.
