The XLVII Congreso de la Sociedad Ibérica de Biomecánica y Biomateriales (SIBB 2025) took place on November 6 and 7, 2025, at the historic Miramar Palace in Donostia–San Sebastián. This edition was co-organized by Dr. Clara García Astrain, researcher at POLYMAT and Dr. Dorleta Jiménez de Aberasturi, from CIC biomaGUNE, who together brought to life an event that gathered national and international experts in biomaterials, biomechanics, and tissue engineering.

Throughout two days of engaging presentations, round tables, and poster sessions, the congress showcased the latest advances in biofabrication, regenerative medicine, nanostructured materials, and 3D/4D printing technologies applied to biomedical research. The meeting fostered collaboration and exchange between academic institutions, research centers, and industry, reaffirming the growing importance of the Basque scientific ecosystem in these multidisciplinary areas.

POLYMAT researchers played an active role across several sessions, presenting innovative work that highlights the center’s contribution to the field of advanced biomaterials:

Garazi Larrañaga – Charge dependent cartilage formation in cell-laden hydrogels enhanced by lupus stimulation

Sandra Camarero Espinosa – From Static to Dynamic: 3D and 4D printing for tissue regeneration

Ana M. Muñoz – 3D Printing of responsive biomaterials for infection sensing

Ane Llucia – Desarrollo de sustitutos para roturas tendinosas mediante bioimpresión 3D

Francesca Perin – Engineering decellularized extracellular matrix for SLA bioprinting of gastric in vitro models

Eduardo Martínez – Eutectozimas: Nuevos materiales híbridos eutéctico-enzimáticos para biocatálisis avanzada

Xabier Larrañaga – Physiologically safe light-induced shape recovery of PLA/PEG blends using gold nanorods

Rakesh Kumar Maji – Supramolecular bioadhesive patches for chronic wounds

In addition to their scientific contributions, Dr. Clara García Astrain moderated the Round Table on Biomaterials: “Transición de modelos 2D a 3D mediante impresión 3D”, which brought together experts to discuss emerging biofabrication strategies and the integration of 4D concepts in tissue regeneration.

The congress also included sessions dedicated to industrial innovation, biomechanical modeling, and young researcher networking, creating a dynamic environment for interdisciplinary collaboration.

The event concluded with a closing ceremony at Miramar Palace and the traditional gala dinner, celebrating the success of an edition marked by scientific excellence, collaboration, and the shared goal of advancing knowledge in biomaterials and biomechanics.

👏 POLYMAT congratulates all participants for their excellent presentations and contributions, and extends special thanks to Dr. Clara García Astrain and Dr. Dorleta Jiménez de Aberasturi for their outstanding organization and leadership.
