Descrizione generale

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.

Applicazioni

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.

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.

Versatile Cell Culture Scaffolds via Bio-orthogonal Click Reactions

Devising biomaterial scaffolds that are capable of recapitulating critical aspects of the complex extracellular nature of living tissues in a threedimensional (3D) fashion is a challenging requirement in the field of tissue engineering and regenerative medicine.
