应用
由亲水性PEG嵌段和疏水性聚(L-交酯)(PLlA)嵌段组成的生物相容性两亲嵌段共聚物。这些材料已被用于药物封装和递送应用的控释和纳米颗粒制剂中。可通过控制每个聚合物嵌段的相对长度来制备具有各种属性的定义明确材料。羟基封端可实现对这些材料进行进一步的化学修饰。
Description
Biocompatible, amphiphilic block copolymer composed of a hydrophilic PEG block and a hydrophobic poly(L-lactide) (PLLA) block. These materials have been used in control release and nanoparticle formulation for drug encapsulation and delivery applications. Well-defined materials with varying properties can be prepared by controlling the relative length of each polymer block. Hydroxyl termination allows for facile further chemical modification of these materials.
