Those biodegradable materials finally form into CO2 and H2O via culture of tricarboxylic acid cycle, which can be excreted from lung, kidney, and skin. Hydroxyacetic acid is a metabolic product of amino acids. Therefore, velocity of bioldegradable materials can be controlled in vivo. The recent contraception focuses on discover a sustained release system of biodegradable materials.
生物可降解材料包括聚乳酸、聚ε-己内酯、乳酸-羟基乙酸共聚物等,这些材料有很好的生物相容性,植入体内后可经生物降解成乳酸单体,经三羧酸循环后最终成为CO2和H2O,经肺、肾、皮肤排泄,羟基乙酸也是机体氨基酸代谢产物,而且生物可将解材料在体内降解速度是可控的,用生物降解聚合物作为药物载体的缓释避孕系统是目前材料学以及避孕节育研究的一大重点。
