Abstract
A method of screening, isolating and purifying rare cells includes obtaining cell groups with rare cells from a sample, removing cells not to be screened from the cell groups, and drawing the remaining cells as a cell suspension sample. An introduction device is activated to load the cell suspension sample onto an optically-induced dielectrophoresis chip including a cell isolation zone having a division arrangement wherein at least one optical pattern is configured on the cell isolation zone for screening, isolating and purifying the rare cells. The at least one optical pattern is configured to migrate, rotate or both. The at least one optical pattern is activated to attract the rare cells into a collection tank on the chip, and a liquid drawing device is activated to draw the rare cells out of the collection tank, thereby obtaining purified rare cells from the sample.
