中文名称：聚乙二醇-b-聚丙交酯(x/y)

英文名称：mPEG-b-PDLLA

嵌段共聚物胶束广泛用于药物递送领域。PEG-PDLLA是一种可生物降解的聚合物胶束，可用作疏水性药物（如紫杉醇）的载体。PEG是亲水性部分，PDLLA是疏水性部分，后者形成负载疏水性药物的胶束核心。

Block copolymer micelles are widely used in the field of drug delivery. PEG-PDLLA is a biodegradable polymer micelle, which can be used as a carrier for hydrophobic drugs such as paclitaxel. Peg is the hydrophilic part and PDLLA is the hydrophobic part, which forms the micellar core loaded with hydrophobic drugs.
