We have presented our last results obtained from our current project NANOCARRIER POLYMERS FOR DENTAL TISSUES REGENERATION (MAT2017-85999-P) at the XVII Jornadas sobre Biomateriales y el Entorno celular. We have met with lifelong friends and young researchers of the Biomaterials field from all over the country. Members of the business sector interested in the new proposals have also attended. This conference day has truly been unforgettable.
