How gaussmeters are being used in biomedical research


Gaussmeters are frequently used in manufacturing QC and test applications. Another area where we are seeing an increasing amount of use is in the medical field. These instruments are being used not only to test the magnetic field uniformity and amplitude of MRI machines but also in academic labs where scientists are using magnetic fields for research into future biomedical diagnosis and treatment applications. (Similarly, we’ve covered how our VSMs have been used for characterizing the behavior of nanoparticles for field-controlled cancer therapies.)

For instance, in the past year, there has been published research in which scientists have used a:

  • Model 455 gaussmeter to measure peak magnetic flux density on streptozotocin-injected lab rats exposed to extremely low-frequency pulsed magnetic fields (ELFPMF); this was part of a study focused on the effects of ELFPMF in treating the symptoms of diabetic nephropathy.
  • Model 455 gaussmeter to verify the field of Helmholtz coils employed in research examining whether pulsed electromagnetic field (PEMF) stimulation enhances the repair efficiency of porous titanium (pTi) implants used to treat bone defects.
  • Model 425 gaussmeter to perform hysteresis loop curve measurements as part of research into the interactions between core-shell magnetoelectric nanoparticles (CSMEN) and biological cells when AC magnetic field is applied.
  • Model 420 gaussmeter to measure the field generated by a Helmholtz coil when researching the promise of different types of giant magneto-resistive (GMR) biosensors for high-sensitivity early disease diagnosis applications.
  • Model 421 gaussmeter to measure the field distribution of magnetic nanoparticles (MNPs) used in research investigating the combined effect of MNPs and near-infrared (NIR) phototargeting on the growth of brain cells.
  • Model 420 gaussmeter to measure static magnetic field (SMF) induction values as part of research into the biological properties of stem cells exposed to 0.5 T SMF.
  • Model 460 3-axis gaussmeter to determine the magnetic flux density of permanent magnet arrays included in an experimental, magnetically actuated drug delivery system for robotic-assisted gastrointestinal endoscopy.
