Abstract

Fundamentally we are exploiting the fact that magnetic nanoparticles generate heat when placed in an alternating magnetic field. Energy from the applied magnetic field is absorbed by the particle and transformed into heat with some efficiency. Generally, the more energy absorbed from the field, the greater the heat generated by the particle.

To synthesize and assess these particles was the purpose of this research. The chemical synthesizes of iron oxide nanoparticles that contain dilute amounts of manganese and cobalt to greatly improve their ability to absorb energy from applied magnetic fields. These particles consist of a solid iron oxide core doped with either Mn or Co, and then coated with another layer of iron oxide doped with either Co or Mn – whichever element is not already in the core. Finally, the whole particle is overcoated in a thin layer of gold to protect the iron oxide from degradation and in turn, protect the cells from dissolved iron. The ultimate purpose was to create particles that are biologically inert while still retaining a functional size. This is what was sought out and will be explored in the research undergone over the past year.
