Scaffold functionalization to support a tissue biocompatibility

The aim of this chapter is to illustrate the most applied methods for covalent and non-covalent functionalization of scaffold surface with biomimetic molecules, including bioactive proteins, peptides, and polysaccharides to improve scaffold biocompatibility. Additionally, the main techniques for surface physicochemical characterization are presented together with the commonly used approaches for in vitro testing of biocompatibility. Finally, new perspectives in scaffold surface functionalization and application of functionalized scaffolds are discussed in the conclusions.
