Abstract
Methods and systems are provided for isolating circulating tumor cells from a peripheral blood supply in order to diagnose early stage cancer and/or evaluate tumor status. In one example, a system for capturing circulating tumor cells includes a substrate having a cell-capturing region, the cell-capturing region having a curved, switchback-like shape and including an array of micropillar structures within the curved, switchback-like shape.
