Abstract
This paper presents a programmable magnetic cell sorter to seperate different-sized cells. The cell sorter consists of a series of seperating units, comprising ferromagnetic nickel lines and current-carrying gold lines. The magnetized nickel lines and the current of gold lines can generate local field and attract the cells coated with magnetic nanoparticles. By changing the current, we could control the local magnetic field, which enables the device to sort the target cell sizes selectively. We successfully demonstrated this scheme by sorting three different sizes (6, 10, and 15 µm in diameter) of magnetic beads under the different current of 21, 37, and 68mA/line to the gold lines in the fabricated microfluidic chip.
