一般描述

聚乙二醇(PEG)是一种亲水性聚合物。它可以通过环氧乙烷的阴离子开环聚合进行合成,从而形成不同分子量和带有各种不同端基的聚合物。当交联成网络时,PEG可具有高含水量,从而形成“水凝胶”。由于它不会引发免疫反应,因此PEG是一种适合生物学应用的材料

应用

聚乙二醇可用于药物制剂,提高药物的溶出率和口服生物利用度。

聚乙二醇可用于高效分离抗癌和抗炎性优异的食用纳米颗粒(ENP)。聚乙二醇是一种拥挤剂(crowding agent),可形成网状网捕获和沉淀纳米囊泡。例如,PEG法可分离姜来源ENP,比超速离心法更加经济实惠。

PEG可作为前体合成可降解水凝胶,用于亲水性高分子药物控释。

特点和优势

  • 高结构柔性
  • 生物相容性
  • 两亲性
  • 高水化性
  • 无空间位阻
