| 초록 | Tissue regenerative materials require many features such as biocompatibility, biodegradability, bio-stability, and rigidity depending on target tissue. Guided tissue regeneration (GTR) membranes have been used to maintain adequate space and prevent ingrowth of soft tissue during bone healing period. Thus, mechanical properties and biological properties are very important for GTR membranes. In order to enhance the mechanical properties of GTR membrane, particularly rigidity, numerous physical and chemical modifications including structure alignment, crosslinking, and compositing with other materials have been carried out. Among them, incorporating additives is one of the simple and effective methods to strengthen GTR membrane. The additive materials for bioengineering are generally strong, biocompatible or bioactive, and functional for the delivery of therapeutic molecules. Graphene is receiving growing attention as a prospective material in biomedical research fields due to its fascinating properties such as high surface area, excellent mechanical strength, extraordinary elasticity, and great electronic conductivity. Recent studies have reported that graphene has potential of improving mechanical properties and osteogenic responses for hard tissue engineering. Moreover, graphene can interact with other materials including biopolymers and therapeutic molecules through covalent and non-covalent bonding. As an additive material, graphene, has advantages of producing nanocomposites with strong interface between polymeric matrix with drug delivery ability. In this presentation we propose an effective method to fabricate graphene-incorporated composites with uniform microstructure. The developed method is suitable to produce bioengineered graphene-based composites with tunable mechanical and physical properties as well as good biocompatibility, thus providing cell-favorable microenvironment for tissue engineering. |
