Enhancement of Cell Migration Rate Toward a Superparamagnetic Scaffold Using LF Magnetic Fields

Recently developed superparamagnetic scaffolds for bone tissue engineering are still a complex object to deal with. Thanks to the possibility of controlling them remotely and directing therapeutic action in a non-invasive way, this work deals with the necessity of a clear definition and quantification of the field gradient, the forces and velocity it could exert on magnetic nanocarriers in a static magnetic field, and the heat and power generated when a time-varying field is applied, better defining the frequency response of magnetic nanoparticles entrapped in a solid matrix.
