Application

O-(2-Azidoethyl)heptaethylene glycol is used to synthesize oligo and poly(ethylene glycol) derivatives that are used as structural units of dendrimers, hydrogels, surface modifiers, self-assembling systems and molecular crosslinkers. This precursor is compatible for acetylene-azide click reactions.

Some of the reported applications include:
  • Synthesis of strain-stiffening hydrogels through self-assembly of oligomers fibres derived from Azido-PEG (n=7).
  • Synthesis of biodegradable tetra-PEG hydrogels for drug delivery system.
  • Synthesis of heterobifunctional oligo(ethylene glycol) linkers for bioconjugation and targeted drug delivery.
  • Preparation of synthetic amphiphiles for programmed pH-dependent dispersions of carbon nanotubes (CNTs).
  • Selective glycoprotein detection through allosteric click-imprinting by using a self-assembled monolayer developed from the above oligomer.
  • Preparation of bioactivated quantum dot micelles containing fluorescent nanocrystals.

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.
