(IMAGE) Universidad Carlos III de Madrid Caption The top image shows the forces generated by an external magnetic field on particles embedded in the material. These interactions are simulated by a computational model that is able to guide the manufacturing and experimental process (middle image). Finally, the generated forces are transmitted to the cells cultured on the smart material (bottom image). This action on the cells will lead to changes or activation of their biological functions, such as proliferation, migration or orientation, among others.
