Microwave Imaging for Monitoring Bone Healing Using Magnetic Scaffolds: An Initial Analysis

Magnetic scaffolds are a particular class of multifunctional and electromagnetic-responsive biomaterials, in which traditional biomaterials are loaded with magnetic nanoparticles. These biomedical devices are able to accelerate bone healing repair under the action of electromagnetic fields. To date, limited efforts have been spent to provide monitoring tools for the follow up of bone tissue regeneration for these theranostic devices. In this work, the possibility of using microwave imaging to monitor tissue regeneration is investigated. In particular, a preliminary analysis on the signal level variations that can be observed during bone regeneration is performed, as this provides the necessary initial guideline to design a monitoring device.
