一般說明

聚乙二醇二丙烯酸酯(PGEDA)用于合成高度交联的水凝胶，该水凝胶用作组织工程中的生物材料。这些水凝胶是使用无细胞毒性的光引发剂形成的。PEG水凝胶可以很容易地与生物活性蛋白和肽共价连接，反过来促进水凝胶表面或内部的特定细胞活性。

應用

这种同双功能PEG可用于水凝胶应用、生物增容作用、硫醇-烯偶合；以及使用交联PEG网络的其他应用。

We present an easy and effective method for the encapsulation of cells inside PEG-based hydrogel microstructures fabricated using photolithography. High-density arrays of three-dimensional microstructures were created on substrates using this method. Mammalian cells were encapsulated in cylindrical hydrogel microstructures of
