BIOMATERIALS AND BIOCOMPATIBLE SYNTHETIC MATERIALS
Learning outcomes of the course unit
The integrated course will provide the main knowledge on osteochondrogenesis and on the biomaterials used for bone and cartilage regeneration and repair. Knowledge on biomaterials applied in general surgery, vascular surgery, surgical hemostasis and ocular surgery will be also provided.
