Abstract:
The disclosure relates to a droplet manipulating device and a method for manipulating a droplet. The droplets manipulating device includes a first magnetic field generator, a second magnetic field generator, and a flow channel. The first magnetic field generator produces a first magnetic field on the droplet, so that the droplet has the direction of magnetic field corresponding to the first magnetic field. Further, the second magnetic field generator produces a second magnetic field on the droplet so as to drive the droplet to be in motion in the flow channel.

Abstract:
A method for manipulating a droplet by a droplet manipulating device including a flow channel, a first magnetic field generator, and a second magnetic field generator is provided. The first magnetic field generator includes two first magnetic field modules and are at two sides of the flow channel. The second magnetic field generator is between the two first magnetic field modules and includes multiple second magnetic field coils. The droplet is provided in the flow channel and includes a magnetic particle. A first magnetic field is produced on the flow channel by the first magnetic field modules, so the magnetic particle in the droplet has the direction of magnetic field corresponding to the first magnetic field. A second magnetic field is produced on the flow channel by the second magnetic field coils, for driving the magnetic particle in the droplet to be in motion in the flow channel.
