Description générale

Poly(ethylene oxide) is a non-ionic hydrophilic linear polymer. It can be prepared by catalytic polymerization of ethylene oxide. Owing to its hydration and swelling properties, it is widely used in controlled drug delivery systems and bioadhesive materials.

Application

PEO can be used to:
  • Prepare polymer brushes with unique wormlike conformation which can be used in cancer drug delivery systems.
  • Synthesize polymer electrolytes for solid-state batteries and fuel cells.
  • Prepare biodegradable PEO/Ag nanocomposites forbiomedical and food packaging applications.

Caractéristiques et avantages

  • High water solubility
  • Non-toxicity
  • Rapid hydration
  • Insensitive to pH of the physiological system

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.
