Biomaterials
本课程系统介绍用于人体内的天然与合成材料，涵盖金属、陶瓷、聚合物、复合材料及生物活性材料的结构与性能。学生学习材料生物相容性、降解机制、界面反应、表面改性等核心概念，掌握植入物材料选型与评价方法。课程结合骨科、心血管、牙科、组织工程支架等应用案例，培养学生在医疗器械研发中的材料设计能力。
This course introduces natural and synthetic materials used in the human body, covering metals, ceramics, polymers, composites, and bioactive materials. Students study biocompatibility, degradation, interface reactions, and surface modification, mastering material selection and evaluation for implants. Applications span orthopedic, cardiovascular, dental, and tissue engineering scaffolds, developing design skills for medical device R&D.
学生选择聚乳酸（PLA）、聚己内酯（PCL）和镁合金三种可降解材料，通过文献调研与实验数据对比其力学性能、降解速率、生物相容性，结合冠状动脉支架应用场景给出推荐方案并撰写技术报告。
Students compare three biodegradable materials—PLA, PCL, and magnesium alloy—through literature review and experimental data on mechanical properties, degradation rate, and biocompatibility. They recommend a material for coronary stent applications and submit a technical report.
