The urgency for cost-effective, rapid, and user-friendly tools for detecting biomolecules is critical due to their essential role in biosensors relying on giant magnetoresistance (GMR) technology. This article presents the performance of a novel configuration for α-amylase assay as the target biomolecule by employing the ICs-based dual chip commercial GMR sensor, which offers a straightforward approach with immediate electrical data output. Magnetite (Fe3O4) magnetic nanoparticles were synthesized using a green approach, employing leaf extract from Moringa oleifera. Meanwhile, the PEG-functionalized green-synthesized Fe3O4 magnetic nanoparticles (Fe3O4/PEG) were used as a magnetic label and produced in an aqua-solution mixture. Each sensor element surface of the dual chip configuration was then exposed to a minute droplet of analyte solution.
