Abstract:
PURPOSE: A filter with a high aspect ratio for capturing cells is provided to prevent blockage of a flow channel due to captured cells or particles by acquiring an enough space. CONSTITUTION: A filter(100) comprises an inlet(122), an outlet(123), a flow channel(124), and a filter part. A sample flows in through the inlet and flows out through the outlet. The flow channel has a first bottom side and a second bottom side facing each other to allow the sample to flow between the inlet and outlet. The filter part is arranged in the flow channel to capture a target cell or a target particle in the sample. The filter part comprises: a barrier which protrudes towards the first bottom side from the second bottom side; and a gap formed between the barrier and the first bottom side.
