Doctor Amir Abdollahi, Lecturer at LaCàN, has participated in a research project at the ICN2. They have resolved one of the great unknowns in bone self-repair: how the cells responsible for forming new bone tissue are called into action. Their work reveals the role of an electromechanical phenomenon at the nanoscale, flexoelectricity, as a possible mechanism for stimulating the cell response and guiding it throughout the fracture repair process. It has potential implications for the prosthetics industry and the development of biomimetic self-healing materials. The findings were published in Advanced Materials.
