Centrifugal microfluidics for sorting immune cells from whole blood.

ABSTRACT: Sorting and enumeration of immune cells from blood are critical operations involved in many clinical applications. Conventional methods for sorting and counting immune cells from blood, such as flow cytometry and hemocytometers, are tedious, inaccurate, and difficult for implementation for point-of-care (POC) testing. Herein we developed a microscale centrifugal technology termed Centrifugal Microfluidic Chip (CMC) capable of sorting immune cells from blood and in situ cellular analysis in a laboratory setting. Operation of the CMC entailed a blood specimen layered on a density gradient medium and centrifuged in microfluidic channels where immune cell subpopulations could rapidly be sorted into distinct layers according to their density differentials. We systematically studied effec
