Highly stable integration of graphene Hall sensors on a | ResearchBunny

Abstract

This paper presents the development of CMOS-compatible graphene Hall sensors integrated with PDMS microfluidics for magnetic sensing in blood. These graphene micro-Hall detectors (µHDs) achieve performance comparable to the best published µHDs, demonstrate robustness in whole blood due to passivation, and enable in-flow detection of magnetic beads. The system's proof-of-concept, validated using magnetic agarose beads on a silicon substrate, showcases its potential for clinical applications with a custom CMOS chip.
