嵌段共聚物膠束廣泛用于藥物遞送領(lǐng)域。PEG-PDLLA是一種可生物降解的聚合物膠束，可用作疏水性藥物（如紫杉醇）的載體。PEG是親水性部分，PDLLA是疏水性部分，后者形成負(fù)載疏水性藥物的膠束核心。

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.
