A mobile immunoassay system which carries out all its procedure on a CMOS chip is proposed. This method utilizes magnetic beads as its assay marker and provides a simplified protocol. The chip is fabricated in a 0.35 μm standard complementary metal-oxide-semiconductor (CMOS) process. Just one post processing, etch back Hall sensor area, enhances its sensitivity and an RF drain current across it lowers...
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 nm 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...
Magnetic beads-based immunoassay has the potential to provide an on-chip immunoassay. After preliminary experiments, it turned out that a Hall sensor which is fabricated on a standard CMOS can provide an acceptable sensitivity to run an assay on the chip. To implement a practical assay platform, a test chip was designed and fabricated.
