Abstract

The purpose of this study was to explore the properties of coated superparamagnetic nanoparticles (SPNs) specifically for their use in thermal-responsive drug delivery systems. Coated, magnetite SPNs were prepared and dispersed in cyclohexane or cetyl alcohol, a solid lipid at the physiological temperatures of 37 °C. The induced temperature change as a function of SPN concentration and external magnetic field and frequency was consistent with theoretical predictions. SPNs dispersed in a solid lipid matrix underwent heating and the associated melting occurred at a temperature suitable for a thermal-responsive drug delivery system.
