Abstract
An electromagnetic sensing device comprising: a reference microfluidic reservoir to receive a reference substance with magnetic nanoparticles; an analyte microfluidic reservoir to receive an analyte and magnetic nanoparticles; a first excitation magnetic coil to subject the reference microfluidic reservoir to an alternating magnetic field at a first frequency; a second excitation magnetic coil to subject the analyte microfluidic reservoir to an alternating magnetic field at the first frequency; a third excitation magnetic coil to subject the reference microfluidic reservoir to an alternating magnetic field at a second frequency distinct from the first frequency; a fourth excitation magnetic coil to subject the analyte microfluidic reservoir to an alternating magnetic field at the second frequency; a first detection magnetic coil to detect a response magnetic field of the magnetic nanoparticles in the reference microfluidic reservoir; a second detection magnetic coil to detect a response magnetic field of the magnetic nanoparticles.
