A micro-fluidic device operable to isolate target cells from a biological fluid comprises: an inlet operable to receive the biological fluid, the biological fluid comprising target cells and other components; a waste outlet operable to receive at least the other components of the biological fluid; a plurality of parallel arrays of cell isolation wells coupling the inlet with the waste outlet, each parallel array of cell isolation wells supporting a flow of the biological fluid from the inlet to the waste outlet in response to a pressure differential thereacross, each array of cell isolation wells comprising a plurality isolation wells, each isolation well being dimensioned to mechanically trap the target cells therein whilst permitting flow of other components of the biological fluid; and at least one pressure maintenance structure operable to assist in maintaining a predetermined pressure differential across each of the plurality of parallel arrays of cell isolation wells. |
