Application

聚乙二醇可用于修饰磁铁矿纳米粒子。在磁核上涂覆PEG外壳可使纳米粒子在保持磁性的前提下具备良好的稳定性。

PEG可用于修饰光催化TiO2纳米粉末，用于制造自清洁涂料。PEG涂覆的TiO2纳米粉末可通过温和条件制备，具有优异的胶体稳定性。

可用作交联剂，制备基于聚N-异丙基丙烯酰胺的热敏型可注射水凝胶。引入PEG提高了水凝胶的化学和机械性能，防止水凝胶在溶胀介质中溶解。这种水凝胶由于生物相容性和生物可降解性，广泛用于生物医学领域。

Features and Benefits

  • 结构柔性高
  • 生物相容性
  • 水化能力高
  • 无任何空间位阻

Versatile Cell Culture Scaffolds: Bio-orthogonal Click

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

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.
