| 제목 | Surface modification of biomaterials by plasma-based ion implantation |
| 초록 | With the increasing demand for improved quality of life, bio-metals and -polymers have been considered suitable implantation materials for the temporary fixation of several types of damaged human tissues. In the field of bone tissue engineering in particular, biomedical devices fabricated by these materials have demonstrated the unique advantages of their mechanical, chemical, and biological properties in fracture fixation, repair, and augmentation. At the initial states of bone healing, the surface of implant plays a critical role in the interaction with surrounding cells and, eventually, the regeneration of the damaged tissue. Therefore, numerous efforts have been concentrated on the surface modification for enhancing the cellular responses. Recently, plasma-based ion implantation techniques have been proposed as an effective strategy to modify the implant surface while maintaining sufficient structural stability of it. Both the morphological and chemical characteristics of the biomaterial surface can be easily changed by ion implantation. Herein, we report, simple and rapid methods of newly developed plasma-based ion implantation methods onto bio-metals and -polymers, and physical, chemical, and biological properties of modified biomaterials are widely explored and investigated. |
