一般描述

聚乙二醇(PEG)是亲水性聚合物。它可以通过环氧乙烷的阴离子开环聚合很容易地合成,得到一系列分子量和各种端基。当交联成网时,PEG可具有很高的含水量,形成“水凝胶”。可以通过电离辐射使PEG交联或通过PEG大分子单体与反应性链端共价交联来引发水凝胶形成。PEG是适合生物学应用的材料,因为它不会引发免疫反应。

应用

PEG被用于修饰治疗性蛋白和肽,以增加溶解度、降低毒性。

光聚合的PEG水凝胶在制备生物活性和免疫隔离的屏障用于细胞包封方面具有新兴应用。

Understanding the interface between DNA and nanomaterials is crucial for rational design and optimization of biosensors and drug delivery systems. For detection and delivery into cells, where high concentrations of cellular proteins are present, another layer of complexity is added.

Hydrogels provide three-dimensional frameworks with tissue-like elasticity and high permeability for culturing therapeutically relevant cells or tissues. While recent research efforts have created diverse macromer chemistry to form hydrogels, the mechanisms of hydrogel polymerization for in situ cell encapsulation remain

Self-organization of kinesin-driven, microtubule-based 3D active fluids relies on the collective dynamics of single microtubules. However, the connection between macroscopic fluid flows and microscopic motion of microtubules remains unclear. In this work, the motion of single microtubules was characterized by

Non-clustered δ1- and δ2-protocadherins, close relatives of clustered protocadherins, function in cell adhesion and motility and play essential roles in neural patterning. To understand the molecular interactions underlying these functions, we used solution biophysics to characterize binding of δ1- and

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.

Designing biomaterial scaffolds mimicking complex living tissue structures is crucial for tissue engineering and regenerative medicine advancements.
