Water based suspensions of iron oxide obtained by laser target evaporation for biomedical applications

Abstract

In this work spherical magnetic nanoparticles (MNPs) of iron oxide were obtained by laser target evaporation technique (LTE). Water based suspensions were prepared on the basis of obtained MNPs and their properties were also studied including inductive heat capacity. Their structure and properties were studied by a number of techniques including magnetometry and heat capacity measurements. Magnetic induction heating experiment show the specific loss power (SLP) value in the narrow range from 1.30 to 1.45W/g for all samples under consideration when using alternating magnetic field of 1.7kA/m and frequency of 210kHz. These parameters insure that LTE MNPs are interesting materials promising for magnetic fluid hyperthermia.
