【摘要】 纳米粒子作为药物和基因的载体显现出极大的潜力并被广泛研究。纳米粒子的超微小体积可使药物输送智能化,例如靶向定位地将药物投递到病灶局部或专一性地作用于靶细胞。纳米粒子的载体材料可屏蔽药物不良气味、维持药物长期缓慢释放、延长药物半衰期和减小毒副作用等。本文将从纳米药物输送、控释制剂的制备和应用前景等方面进行综述。更多还原

【Abstract】 Nanoparticule (NP) as a drug and gene carrier has shown great potential and has been widely studied. Due to its ultra-small size, NP can achieve intelligent delivery of drugs, such as deliver drug site-specifically to disease focus or targeted tissue, even into target cells. The carrier materials of NPs provide it with such advantages as shielding odor, long-term sustained releasing of drug, lowering uoxicity,extend biologic half life of drug and gene, etc. This review emphasizes the manufacturing techniques and application of nanoparticles as drug and gene delivery system.更多还原
