Scientists from 4D-BIOMAP, an ERC research project at the Universidad Carlos III de Madrid (UC3M), have developed a new experimental method, based on magneto-active polymers, to study cellular behavior. These compounds, which consist of a polymeric matrix (e.g., an elastomer) containing magnetic particles (e.g., iron), mechanically react by changing their shape and stiffness. This system could be used to study complex scenarios (such as brain trauma, wound healing, etc.) or to influence cellular responses, guiding their functions.
