Abstract
This paper presents an on-chip magnetic cell sorting system for the sorting of cells based on a variety of surface markers. A polymer lab on a chip integrated with an electroplated array of Ni/Fe permalloy has been designed, fabricated, and characterized for the separation of cell substitutes at a variety of flow rates and incubation times. The system sequentially labels cell substitutes with magnetic beads and sorts them, repeating this process to sort for a variety of surface markers. Flow rates and incubation times were varied to characterize the system and produce the best combination of high specific capture and low nonspecific capture. The separation system developed on polymer is selective and efficient while being low cost, portable, and fabricated in a modular structure that can be integrated with other cell handling processes.
