Multiple separation device and method of separating blood cancer cell

摘要

The present inventive concept provides a multiple separation device and a method of separating a blood cancer cell using the same. In the device and the method, a blood sample is put in a fine channel and then cancer cells can be separated according to the type of cancer by controlling a flow velocity of the blood or a magnetic force of ferromagnetic pattern.

主权项

1. A method of separating a blood cancer cell comprising:
producing a compound solution including cancer cells with which a magnetic nano-bead is combined by mixing the magnetic nano-bead with which an antibody specifically reacting to a cancer cell is combined with blood to be tested; injecting the compound solution into a channel in which ferromagnetic patterns are disposed on a bottom surface of the channel; and capturing cancer cells in the channel depending on the type of the cancer cells by varying an amount of magnetic force applied to the compound solution according to a location of the channel.
