Synthesis means to obtain nanomaterials employed for cancer treatment by magnetic hyperthermia

Abstract

The present bibliographical compilation shows how different nanomaterials are used in the hyperthermia treatment for cancer, among which, the most employed are the materials with magnetic properties. Due to their superparamagnetic behavior, they can be exposed to a magnetic field, which in turn produces an increase in temperature up to a maximum of 46 °C. This temperature causes the elimination of tumor cells; this process is known as magnetic hyperthermia. The problem to be solved from the point of view of the synthesis is to find a simple method which allows a control of particle size to get the desired biocompatibility properties. It is concluded that the obtaining of materials for hyperthermia applications is given by various methods; among which stand the sol-gel method, coprecipitation, thermal decomposition, and others. The latter is the best option because it allows a control of particle size. In addition, it is possible to improve the desired biocompatibility or magnetic properties by surface coatings or doping.
