Abstract: The invention is a novel and non-obvious design and implementation of an inductive sensor for quantifying magnetic particles. The invention parts way from the conventional methods of using wounded coils to a design that is compatible with an integrated circuit (IC) chip fabrication processes and/or printed circuit board (PCB) manufacturing. The increased accuracy from these fabrication methods provides a significant improvement to sensor sensitivity. In addition, the design of the inductive sensor enables easy integration with lateral flow assay (LFA) technology. The sensor can be applied to detect and quantify molecules to provide information on health, hazard or safety.
