The subject matter of this invention relates to block copolymers (BCPs) and, more particularly, to block copolymers capable of self-assembly into nanoparticles for the delivery of hydrophobic cargos. The BCPs include a hydrophobic block that contains a thioether functional group that is susceptible to oxidation, transforming the solubility of the block from hydrophobic to hydrophilic, thereby releasing the hydrophobic cargo of the nanoparticle.
本发明的主题涉及嵌段共聚物(
BCPs),更具体地说,涉及能够自组装成用于输送疏
水性货物的纳米颗粒的嵌段共聚物。
BCP 包括疏
水性嵌段,该嵌段含有
硫醚官能团,
硫醚官能团易被氧化,使嵌段的溶解性从疏
水性转变为亲
水性,从而释放出纳米粒子中的疏
水性货物。
