Biocompatibility of single crystalline Fe Pd ferromagnetic shape

摘要

Controllable by an external magnetic field, ferromagnetic shape memory materials reveal a highnpotential for actuators in biomedical applications. Simulated body fluid u0002SBFu0003 and cell tests werenperformed to assess the biocompatibility of Fe70Pd30 ferromagnetic shape memory thin films asngrown on MgO substrates. Calcium-phosphate aggregates were detected on the film surface afternsoaking in SBF. Biocompatibility tests with NIH 3T3 fibroblasts revealed adhesion and proliferationnon the film surface but morphological modifications with a reduced cell size became evident as wellnas changes in cell viability for continuous and noncontinuous FePd films. The results are comparednto FePd on SiO2.© 2010 American Institute of Physics. u0004doi:10.1063/1.3435260
