Abstract
Creating ‘smart’ biomedical devices with the potential for controlled actuation in vivo has been a long-standing scientific pursuit in therapeutic medicine. The present work focuses on a bone regeneration scaffold based on ferromagnetic fibres designed to induce in vivo modelling of in-growing periprosthetic bone by the application of an external magnetic field of clinical magnitude. We present the conceptual basis of such a ‘magneto-active scaffold’, the properties of prime interest and how these properties can be controlled.
