报告摘要：
The development of modern biomaterials started more than 40 years ago. Over the past few decades, we have witnessed extensive efforts in biomaterials R & D. Some of these efforts have paid off and hence patients benefit now from new and high performance biomaterials. However, there is still much room for further explorations into better biomaterials for various applications: tissue repair, tissue regeneration, drug delivery, cancer detection and treatment, etc. There are many strategies in biomaterials R & D for improving the biomaterials currently in use and for designing and developing new biomaterials. In this seminar, some of our work in the following selected areas will be presented:
·Metallic implants provide the strength and toughness which are required in load-bearing parts of the body. However, there are concerns over ion release and corrosion products from implantable metals. Research has been conducted on forming coatings on metals using various techniques. Some coatings can produce bioactivity for metal implants, thus promoting bone formation in vivo, and at the same time limit cytotoxic ion release.
·Using natural tissues as templates, novel, “designer” biomaterials can be developed. Many non-porous bioactive ceramic-polymer composites have already been investigated for bone substitution. Particulate bioceramics (e.g., hydroxyapatite) can be incorporated into biocompatible (and biodegradable) polymers. By choosing constituent materials for composites and controlling processing parameters, the biological and mechanical performance of bioactive composites can be tailored to meet various clinical requirements.
·Tissue engineering holds the promise to solve problems of tissue loss and organ failure. One key issue in scaffold-based tissue engineering is the development of scaffolds for seeding cells and for tissue growth. There are a number of polymers for tissue engineering scaffolds and various techniques have been used to produce scaffolds. One strategy is to use industrial processes to produce good-quality bioactive nanocomposite scaffolds. These scaffolds with suitable surface modifications exhibit enhanced biological performance.
On the basis of our own biomaterials research and in the context of worldwide biomaterials R & D, an outlook will be given in areas in which we have been conducting our research work.
