两亲性嵌段共聚物(AmBC)由两种化学上不同的均聚物嵌段组成。嵌段之一是亲水的,另一个是疏水的。这些大分子溶于水介质时具有自组装的特性。PEG-PLGA是最常用于药物递送应用的可生物降解的两亲嵌段共聚物之一。PEG是亲水部分,PLGA是疏水部分。
应用
Amphiphilic block copolymers (AmBC) are made up of two chemically different homopolymer blocks. One of the block is hydrophilic and the other one is hydrophobic. These macromolecules have the properties to self-assemble when dissolved in an aqueous media. PEG-PLGA is one the most commonly used biodegradable amphiphilic block copolymers for drug delivery applications. PEG is the hydrophilic part and PLGA is the hydrophobic part.Used in the synthesis of targeted nanoparticles which are used for differential delivery and controlled release of drugs.
