일반 설명

Poly(ethylene oxide)(PEO) is a high molecular weight, non-ionic water-soluble polymer. It forms agel on hydration and shows good swelling capacity. PEO polymers are non-toxicand widely used in drug delivery systems to enhance drug solubility.

애플리케이션

Poly(ethylene oxide) can be used to prepare:
  • Bioabsorbable and injectable hydrogels for sustained drug release.
  • PEO/graphene oxide composite electrolyte membrane for fuel cells.
  • Poly(ethylene oxide)-b-poly(ε-caprolactone) (PEO-b-PCL) diblock copolymer. Losartan potassium encapsulated (PEO-b-PCL) copolymer can be used as a drug carrier.

Electrospinning: Enabling Nanostructured Materials

Electrospinning technique applications discussed, emphasizing control of nanofibers and assembly into 3D architectures.

2D 및 3D 세포 배양을 위한 분해성 폴리(에틸렌 글리콜) 하이드로겔

조직 공학과 약물 전달과 같은 생명 공학의 진보는 다양한 기능성 바이오 소재에 대한 수요 증가를 동반합니다. 연구의 집중 관심 대상이 되어온 바이오 소재의 한 분야는 바로 하이드로겔으로, 화학적으로나 물리적으로 세포의 자연 환경과 유사하게 닮아 있기 때문에 세포를 키우는 토대로 사용될 수 있습니다. 본 기술 문서에서는 일반적으로 면역 반응을 유발하지 못하기 때문에 생물학적 용도로 적합한 PEG(폴리에틸렌 글리콜) 하이드로겔에 대해 상세하게 논의합니다. PEG는 쉽게 이용할 수 있으며, 손쉽게 고분자를 수정하여 세포 배양을 위한 2D 및 3D 뼈대를 포함한 하이드로겔 구성에 광범위하게 사용할 수 있습니다. 또한 분해성 결합을 통해 치료제 출시를 위한 다양한 응용분야에도 도움을 줍니다.

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.
