Abstract

Candidate cells, such as circulating tumor cells (CTCs), present with blood are captured using a multiple stage device, having successive stages configured to deviate candidate cells out of the blood while slowing down the flow rates of the deviated resultant for easier capture of CTCs through progressive stages. The devices can include separation channel and deviation channels formed of micro-post patterns dimensioned to deviate different desired candidate cells for analysis.
