一般描述

聚环氧乙烷（PEO）2是一种高分子量、非离子水溶性聚合物。它在水化时形成凝胶，并具有良好的膨胀能力。EPO聚合物无毒，广泛用于药物递送系统以改善药物可溶性。

应用

聚环氧乙烷可用于制备：
  • 用于药物缓释的可生物吸收、可注射水凝胶。
  • 用于燃料电池的PEO/氧化石墨烯复合电极膜。
  • 聚环氧乙烷-b-聚ε-己内酯（PEO-b-PC）二嵌段共聚物。内含氯沙坦钾的（PEO-b-PCL）共聚物可用作药物载体。

Previous studies have demonstrated that Separan AP-30, a drag-reducing polymer, significantly decreased the formation of atherosclerotic plaques in rabbits fed a high-cholesterol diet. Furthermore, Separan AP-273, a polymer similar to but longer than Separan AP-30, markedly increased cardiac output in

Electrospinning: An Enabling Technique for Nanostructured Materials

In this article, we discuss issues critical to successful application of the electrospinning technique, including control of individual nanofibers to form secondary structures and assembly of nanofibers into 3D architectures.

Electrospinning: An Enabling Technique for Nanostructured Materials
Degradable Poly(ethylene glycol) Hydrogels for 2D and 3D Cell Culture

Progress in biotechnology fields such as tissue engineering and drug delivery is accompanied by an increasing demand for diverse functional biomaterials. One class of biomaterials that has been the subject of intense research interest is hydrogels, because they closely mimic the natural environment of cells, both chemically and physically and therefore can be used as support to grow cells. This article specifically discusses poly(ethylene glycol) (PEG) hydrogels, which are good for biological applications because they do not generally elicit an immune response. PEGs offer a readily available, easy to modify polymer for widespread use in hydrogel fabrication, including 2D and 3D scaffold for tissue culture. The degradable linkages also enable a variety of applications for release of therapeutic agents.

Versatile Cell Culture Scaffolds via Bio-orthogonal Click Reactions

Devising biomaterial scaffolds that are capable of recapitulating critical aspects of the complex extracellular nature of living tissues in a threedimensional (3D) fashion is a challenging requirement in the field of tissue engineering and regenerative medicine.
