Heat generation of surface-modified magnetic .gamma.-Fe2O3 nanoparticles in applied alternating magnetic field
Original language description
In this report, we show preparation of colloidally stable poly(N,N-dimethylacrylamide-coacrylic acid) (DMA)- and D-mannose (MAN)-coated maghemite nanoparticles and their ability to generate heat in an alternating magnetic field, which could make the particles applicable for hyperthermic therapy of cancer. The particles are obtained by coprecipitation reaction and characterized by transmission electron microscopy, dynamic light scattering, and AC calorimetric measurement of heat generated by the particles. While the dry particles were ca. 10 nm in diameter, their hydrodynamic size in water was within the range of 100 nm. Heating characteristics were measured in an LC circuit with a maximum field intensity of 6.8 kA . m(-1) and frequency 190 kHz. The specific absorption rates of gamma-Fe2O3, PDM@gamma-Fe2O3, and MAN@gamma-Fe2O3 nanoparticles were extrapolated to 10 kA . m(-1), reaching about 15 W . g(-1).
