Abstract

In this study, the magnetic induction heating of cobalt ferrite nanoparticles with or without silica coating was analyzed for evaluating the feasibility of these materials to be used for magnetic hyperthermia. Particles of approximately 14 and 40 run were evaluated. For this purpose, we used a magnetic induction system to obtain the specific absorption rate (SAR) values. Two different amplitudes of 35 mT and 63 mT at 180 kHz were used. Our results showed the smaller particles exhibiting the higher SAR value, independent of the intensities applied. Moreover, there was no significant change in the SAR values for both particle sizes in presence of silica. However, silica increased the hydrolytic degradation.

Keywords: cobalt ferrite, hyperthermia, magnetic induction, nanomaterials, ferromagnetism.

 

Resumen

En este estudio, el calentamiento por inducción magnética de nanopartículas de ferrita de cobalto con o sin recubrimiento de sílice fueron analizados para evaluar la viabilidad de estos materiales para ser utilizados en tratamiento de hipertermia magnética. Las partículas evaluadas tienen un tamaño entre 14 y 40 nm aproximadamente. Para este propósito, se utilizó un sistema de inducción magnética obteniendo la tasa de absorción específica valores (SAR, por sus siglas en inglés). Se utilizaron dos diferentes amplitudes de 35 mT y 63 mT a 180 kHz. Estos resultados muestran que las partículas mas pequeñas presentan el valor más alto de SAR, independiente de las intensidades aplicadas. Por otra parte, no hubo ningún cambio significativo en los valores de SAR para ambos tamaños de partículas cuando estas partículas contienen sílice. Sin embargo, sílice aumento la degradación hidrolítica.

Palabras clave: ferrita de cobalto, hipertermia, inducción magnética, nanomateriales, ferromagnetismo.
