General description
Application
It can be used to modify the surface of photocatalytic TiO2 nanopowder for its application in self-cleaning paints. PEG-coated TiO2 nanopowder can be prepared under mild conditions and show excellent colloidal stability.
It can be used as a cross-linker to prepare poly(N-isopropylacrylamide) based thermosensitive injectable hydrogels. The addition of PEG improves the chemical and mechanical properties of hydrogel and prevents it from dissolving in the swelling medium. Owing to their biocompatibility and biodegradability, these hydrogels are widely used for biomedical applications.
Features and Benefits
- High structural flexibility
- Biocompatibility
- High hydration capacity
- Devoid of any steric hindrance

ポリエチレングリコール（PEG）は、生物学的、化学的応用や医薬品開発に有用な化学的性質を有するエチレンオキシドと水との縮合ポリマーです。研究用途にPEGを使用する際に考慮すべき4つのポイントをご紹介します。
複雑な生体組織構造を模倣する生物材料足場の設計は、組織工学や再生医療の進歩にとって極めて重要です。
ポリエチレングリコールは入手が容易で、簡便に修飾が可能なポリマーであり、組織培養用2次元、3次元の足場をはじめとするヒドロゲルの作製に広く使われています。
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.
