Towards industrial production: An additive approach for magnetic particle spectrometers

Magnetic particle spectroscopy is an innovative method for characterizing magnetic nanoparticles with potential medical applications. Traditional methods for instrumentation face challenges such as labor-intensive coil manufacturing, high costs, high tolerances and setup time. This study introduces a new approach using additive manufacturing to create rectangular nested coils, enhancing performance and reducing production complexity. The coils, printed with conductive and dielectric inks, allow for modular configurations and improved sensitivity. Results demonstrate a sufficient signal-to-noise ratio and effective cancellation of excitation frequencies. This presented technique addresses issues of fine-tuning and manufacturing discrepancies while enabling modular and flexible setups tailored to researchers’ specific needs.
