The field of magnetic hyperthermia has attracted a lot of attention in the past thirty years. It is an alternative cancer therapy method that proposes placing magnetic nanoparticles (MNP) in tumor cells under an environment of an alternating magnetic field. As the direction of the magnetic field alternates, MNPs undergo magnetic hysteresis losses, and these loses are dissipated to the surroundings as thermal energy. One of the biggest challenges to this field is the localization of MNPs in targeted tumor cells. Historically, scientists have had issues concentrating MNPs within tumor cells to produce sufficient heat for complete apoptosis. This inevitably leads to higher applied dosage of MNPs in this form of treatment. Our project aims to tackle this problem by introducing viral MNPs into magnetic hyperthermia. Viral MNPs are nothing but MNPs attached to viruses that are mostly found to be non-harmful to humans. Viral MNPs have been worked on for quite some time, but their functions are mostly limited to ''in vivo'' MRI imaging and targeted gene delivery. Using viral MNPs, our approach can potentially concentrate MNPs in targeted tumor cells, thereby achieving the level of heat necessary for effective cell apoptosis yet at the same time, lowering the minimum MNP dosage required for the treatment.

Introduction

The field of magnetic hyperthermia has attracted a lot of attention in the past thirty years as an alternative cancer therapy method. Magnetic hyperthermia proposes the placement of magnetic nanoparticles (MNP) in tumor cells under an alternating magnetic field. As the direction of the magnetic field alternates, MNPs undergo magnetic hysteresis losses that are dissipated to local surroundings as thermal energy. One of the biggest challenges to this method is the localization of MNPs in targeted tumor cells. Historically, scientists have had issues concentrating MNPs within tumor cells to produce sufficient heat for complete apoptosis. This inevitably leads to higher applied dosage of MNPs in this form of treatment. Our project aims to tackle this problem by introducing viral MNPs into magnetic hyperthermia. Viral MNPs are nothing but MNPs attached to viruses that are mostly found to be non-harmful to humans. Viral MNPs have been worked on for quite some time, but their functions are mostly limited to in vivo MRI imaging and targeted gene delivery. Using viral MNPs, our approach can potentially concentrate MNPs in targeted tumor cells, thereby achieving the level of heat necessary for effective cell apoptosis yet at the same time, lowering the minimum MNP dosage required for the treatment.
