New frontiers for hyperthermia-based therapies

Project Director: Dr. Andrei KUNCSER

Enhancing the Specific Absorption Rate (SAR) of magnetic structures is essential for the development of promising hyperthermia-based cancer therapies with magnetic nanoparticles (MNPs), currently still under  clinical trials. Depending on the involved heat transfer mechanism, superparamagnetic relaxation time as well as the coercivity of MNPs can be conveniently used for SAR tuning.
Up today, it has been demonstrated that the two parameters do not depend only on the type of MNP but are affected also by inter-particle interactions (theoretical framework developed by the proposer).
The present project aims to find new ways for tuning SAR, via the above mentioned parameters, by a suitable long-range organization of magnetite MNPs (e.g. MNPs grouped in circles, ellipsoids, spheres, rectangles etc). It is estimated that successful implementation of the project will boost the future development of hyperthermia-based cancer treatments. Moreover, computational methods and experimental methodology developed during the project will be essential in any field involving morphological characterization of nanoparticles.

The project has two main components:

1. development of new methods for morpho-structural data analysis involving electron microscopy and micromagnetic simulations, backed up by in-house designed software.
2. indicating new ways for a fine tuning of the heat transfer mechanisms of MNPs via morpho-structural and organization/configuration aspects.
