BPN475: A CMOS Magnetic Sensor Chip for Biomedical Assay


This project aims to develop a compact CMOS biosensor for robust detection of micron-sized paramagnetic beads which are used as labels for target analyte in biomedical applications.No external magnet, reference sensors or calibration is required. A 4.5-um bead is detected in 16 ms with probability of detection error < 0.1%. The ultimate goal of this project is to integrate the CMOS sensor chip with micro-fluidic system and demonstrate a lab-on-a-chip platform.
