Application

Poly(ethylene glycol) methyl ether can be used:
  • As a chain transfer agent to synthesize amphiphilic block copolymers by metal-free ring-opening oligomerization.
  • As a precursor to prepare retinoic acid-polyethylene glycol nanoassembly as an efficient drug delivery system.
  • To prepare diblock copolymer with polylactic acid, which can be applied in the field of tissue engineering and drug delivery.

Biofouling control essential for device performance and safety; minimize accumulation of biomolecules and bioorganisms.

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.

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