近年来,人们研究了一种无毒且能生物降解的药物载体一脂质体(Liposome),从而使药物能选择性地到达靶部位发挥有效的作用。脂质体作为药物载体,它具有一个立体结构系统,使药物能被保护在很好的空间内,保持其功能。脂质体它是由生理性物质磷脂质类组成。脂质体在血液中稳定,能随着循环通过细胞“内吞”、“融合”及类脂质交换等作用而进入细胞,具有通过体内各屏障的能力。改变脂质体组成,大小、表面电荷等特性,可以改变
In recent years, people have studied a non-toxic and biodegradable drug carrier-Liposome, so that the drug can selectively reach the target site and play an effective role. As a drug carrier, liposomes have a three-dimensional structure system, so that the drug can be protected in a good space and maintain its function. Liposomes It is composed of physiological substances phospholipids. Liposomes are stable in the blood and can enter the cells through the “endocytosis”, “fusion” and lipid exchange of cells through the circulation, and have the ability to pass through various barriers in the body. Changes in liposome composition, size, surface charge, etc., can change
