A comparative study of magnetic transferability of superparamagnetic nanoparticles

The aspect of magnetic transferability was established using an automated magnetic particle transfer workstation. Maghemite (γ-Fe2O3) nanoparticles were synthesized via conventional co-precipitation procedure. Their transferability was determined in addition to several commercial nanoparticles that ranged in diameter, surface functionality, and composition. Transmission and scanning electron micrographs and infrared spectrum, respectively, provided size and surface information on the synthesized particles for comparison to commercially available magnetic nanoparticles.
