Bacterial nanocellulose is an emergent biocompatible natural polymer with increasing applicability in the healthcare sector. A potential innovative application can be found in the design of surgical meshes for the treatment of abdominal hernias. Researchers from ICMAB-CSIC and B. Braun Surgical, a leading manufacturer of medical devices for wound closure, have collaborated to develop a bio-based surgical mesh with this biomaterial. First results from an in vivo animal study yield promising outcomes.
