Abstract

The purpose of this work is in-plane manipulation of dispersed magnetic beads on a chip. This makes an immunoassay chip that completes all its procedures on itself and eliminates any off-chip components. A test chip was drawn in a 180 μm standard complementary metal oxide semiconductor process and tested. Beads with a diameter of 2.8 μm were diluted and applied to the chip. The chip successfully manipulated them with an affordable current down to 5 mA.
