挤出原理
Extrusion Principle
脂质体挤出的原理在于，通过一定的挤出动力源将脂质体样品粒子进行挤压，使其在一定压力条件下通过PC滤膜， 此压力作为粒子过膜过程中的剪切力可使其达到粒径控制的效果。不论形态、大小和分布都可得到极大改善。
The principle of liposome extrusion is that the particles of liposome sample are extruded by a certain extrusion power source to pass through the PC membrane under a certain pressure. The pressure acts as the shear force in the process of the particles passing through the membrane, which can achieve the effect of particle size control. The shape, size and distribubtion can be greatly improved.
