Antibacterial and antifouling catheter coatings using surface grafted PEG-b-cationic polycarbonate diblock copolymers.

abstract：:Recently, chitosan-gelatin scaffolds have gained much attention in various tissue engineering applications. However, the underlying cell-matrix interactions remain unclear in addition to the scaffold degradation and mechanical characteristics. In this study, we evaluated (i) the degradation kinetics of chitosan and ch...
