Biomaterials’ clinical outcome is determined by surface interactions with bio-entities (proteins, bacteria, cells, ...). Functionalization of biomaterial surfaces and natural tissues with bio-inspired bioactive molecular systems is a central topic in the 2BI lab. We have designed technologies using peptides, recombinant biopolymers, and proteins to tailor physical and (bio)chemical properties at the material/tissue interface. We are also combining stem cells and surface functionalization technologies to improve performance of devices and scaffolds. Translational potential of our technologies is a key design parameter and goal.
