Finally, the remaining amine groups are acetylated to ensure that the complex particles do not bear any surfacecharges.
最后,科学家将剩余的氨基进行乙酰化,这保证了复杂粒子不会受到表面电荷影响。

Poly (lactic acid) microspheres with different surfacecharges have been prepared by using cationic, anionic or nonionic surfactants as the microspheres' surface stabilizers.
采用不同的表面活性剂制备得到不同表面电荷性质的聚乳酸微球。
