Hereinafter, the operation flow of the present invention will be briefly described based on the details described above.

FIG. 8 is a schematic operation flowchart of a method of driving a nano-particle concentration device according to an embodiment of the present invention.

The driving method of the nanoparticle concentration apparatus shown in FIG. 8 can be performed by the nanoparticle concentration apparatus 100 described above. Therefore, the contents described for the nanoparticle concentrating apparatus 100 can be similarly applied to FIG. 8 even if omitted below.

Referring to FIG. 8, in step S810, a magnetic field control signal may be generated through the controller 130. FIG.

At this time, in step S810, the controller 130 may generate a control signal for controlling the type of the magnetic field generated from the magnetic field generator 110 to a frequency of 30 Hz or less as a first type. The control unit 130 may generate a control signal for controlling the frequency of 30 Hz or less and then generate a control signal for controlling the type of the magnetic field to a frequency between 100 kHz and 300 kHz as the second type.

Next, in step S820, a magnetic field can be generated through the magnetic field generating section 110 based on the magnetic field control signal generated in step S810.

At this time, in step S820, a magnetic field corresponding to a frequency of 30 Hz or less can be generated through the magnetic field generator 110 based on the first type control signal. In addition, in step S820, a magnetic field corresponding to a frequency between 100 kHz and 300 kHz may be generated through the magnetic field generator 110 based on the second type of control signal.

At this time, in step S830, the magnetic substance 120 is magnetized by the magnetic field corresponding to the first type, so that the nanoparticles containing the drug can be concentrated in the magnetic field region s formed by the magnetic substance 120. [

In addition, in step S830, the magnetic substance 120 may be magnetized or demagnetized by the magnetic field corresponding to the second type to generate heat from the magnetic substance 120. [ Accordingly, the heat generated from the magnetic substance 120 can be conducted to nanoparticles concentrated in the magnetic field region (s), thereby more effectively inhibiting the proliferation of cancer cells and necrosing cancer cells.

In addition, although not shown in the drawing, the driving method of the nano particle concentrating apparatus according to an embodiment of the present invention may further include a step of changing the type of the magnetic field generated from the magnetic field generating unit 110.

The type of the magnetic field can also be controlled to operate with a preset type of magnetic field for a predetermined time. In addition, the type of the magnetic field can be controlled so that the frequency of the magnetic field changes at predetermined time intervals. A more specific example of this has been described in detail above, and the following description will be omitted.
