General description

Poly(oligo(ethylene glycol) methacrylate) (POEGMA) is a family of polymers consisting of a hydrophobic methacrylate backbone and hydrophilic ethylene oxide (EO) side groups with highly branched architecture. The highly branched architecture with a high density of oligo EO moities enhances the solubility of the polymer in water.

Application

  • Drug delivery- enhances the stability and delivery of siRNA and eliminates PEG antigenicity
  • Biosensor coatings- provides an anti-fouling surface
  • Stimuli-responsive hydrogels for tissue engineering, drug delivery, and other biomedical applications
Poly(oligo(ethylene glycol) methyl ether methacrylate) (POEGMA) is a family of polymers consisting of a hydrophobic methacrylate backbone and hydrophilic ethylene oxide (EO) side groups with highly branched architecture . The side chain EO segments enhance the solubility of the polymer in water , exhibiting many interesting properties such as non-fouling , stealth, anti-PEG antibodies & thermo-responsive behaviors.

Features and Benefits

  • Highly branched architecture and high density of oligo ethylene oxide moieties
  • Water soluble
  • Nonfouling and thermo-responsive behaviors
  • Viable alternative to PEG in biological and biomaterial applications

Reactive electrospinning is demonstrated as a viable method to create fast-responsive and degradable macroporous thermoresponsive hydrogels based on poly(oligoethylene glycol methacrylate) (POEGMA). Hydrazide- and aldehyde-functionalized POEGMA precursor polymers were coelectrospun to create hydrazone cross-linked nanostructured hydrogels in a single processing

Understanding of the temperature-induced phase transition of poly(oligo(ethylene glycol) methyl ether methacrylate) (POEGMA) random copolymers with varied composition remains largely incomplete. Upon heating they can form either macroscopically phase-separated aggregates or micelles. We examined the effect of polymer architecture by

The delivery of therapeutic peptides and proteins is often challenged by a short half-life, and thus the need for frequent injections that limit efficacy, reduce patient compliance and increase treatment cost. Here, we demonstrate that a single subcutaneous injection of
