Thanks to its unique versatility, nanotechnology offers new diagnosis and therapy alternatives for cancer treatment, even in different stages of the disease. However, these theranostic properties are often limited by the lack of an accurate method to detect and explore their properties. The main purpose of this project is optimizing and applying the AC Biosusceptometry (BAC) technique as an in vivo detection and monitoring system for magnetic nanoparticles (MNP) tumor accumulation. The Biosusceptometry system, extensively applied to physiological gastrointestinal tract studies, offers a viable, portable and versatile alternative to monitor MNP distribution through tissues and organs of interest. Thus, in this project, we aim to validate the BAC system as a detection and monitoring tool for tumor accumulation of magnetic nanoparticles in mice. Also, by optimizing the nanoparticles coating process, we intend to enhance tumor accumulation for further hyperthermia (HT) treatment. Since HT is dependent upon particles concentration in the tumor site, we strongly believe we can increase treatment efficiency by applying real time MNP concentration monitoring to enhance heat delivery.
