Opis ogólny

Poly(ethylene glycol) (PEG) is a biocompatible inert synthetic polymer with repeating units of ether oxygen (-CH2-CH2-O-). It can be synthesized via anionic polymerization of ethylene oxide. It is extensively used in biological and medical applications due to its non-immunogenicity and high water solubility.

Zastosowanie

PEG can be used to functionalize magnetite nanoparticles. The coating of the magnetic core with PEG provides good stabilization while maintaining the magnetic properties of the nanoparticles.

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.

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.

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.
