General description

Polyethylene glycol (PEG) is a hydrophilic polymer. It can be easily synthesized by the anionic ring opening polymerization of ethylene oxide, into a range molecular weights and variety of end groups. When crosslinked into networks PEG can have high water content, forming “hydrogels”. Hydrogel formation can be initiated by either crosslinking PEG by ionizing radiation or by covalent crosslinking of PEG macromers with reactive chain ends. PEG is a suitable material for biological applications because it does not trigger an immune response.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. Polyethylene glycol (PEG) is an eco-friendly, biodegradable polymer widely used in pharmaceuticals and cosmetics. Its non-toxic nature and versatility make it a sustainable choice, derived from renewable resources, contributing to greener product formulations. Click here for more information.

Application

PEG has been used to modify therapeutic proteins and peptides to increase their solubility and lower their toxicity.

Photopolymerized PEG hydrogels have emerging applications in the fabrication of bioactive and immunoisolating barriers for encapsulation of cells.

Versatile Cell Culture Scaffolds: Bio-orthogonal Click

Designing biomaterial scaffolds mimicking complex living tissue structures is crucial for tissue engineering and regenerative medicine advancements.

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.
