Microwave Imaging for Bone Regeneration Monitoring Using Magnetic Scaffolds: Preliminary Results

Biomedical applications, both in therapy and diagnosis, are increasingly using magneto-dielectric composite materials. One notable example is magnetic scaffolds (MagS), which consist of a biomaterial matrix embedded with magnetic nanoparticles. These devices respond to external magnetic fields, triggering specific biological effects. This contribution explores the potential of using microwave imaging as a tool for monitoring bone healing and regeneration. In this context, implanted MagS, which are widely used to promote bone healing, are investigated. By leveraging their unique ability to respond to external magnetic fields, we demonstrate that MagS degradation, directly linked to bone healing, can be tracked through their microwave response. Preliminary results are reported in this paper.
