BIOLOGICAL, BIOINSPIRED AND BIOMATERIALS
Welcome to the multidisciplinary research group B3Mat (Biological, Bioinspired and Biomaterials) of the Adolfo Ibáñez University, located in the city of Viña del Mar, Chile.
Our objective is to develop strategies to value the use of natural and artificial biomaterials for potential biotechnological and biomedical applications. For that we have established a multiscale and integrative technological platform of experimental biomechanical models, in vitro biological models and computational models.
At B3mat we firmly believe that science is a social and collaborative activity, so our work not only seeks to conduct high-level research, but also to help it reach citizens.
We are a research group committed to both inclusion and the environment as well as education and transfer of scientific knowledge to our community.
The members of our research group come from various branches of science and engineering, forming a multidisciplinary team. In addition, they train undergraduate and postgraduate students, both at the Adolfo Ibáñez University and others nationwide. They also actively collaborate with researchers from Chile and abroad.
