Amy Van Hove, Brandon Wilson and Danielle Benoit, Ph.D. have published an article entitled, Microwave-assisted Functionalization of Poly(ethylene glycol) and On-resin Peptides for Use in Chain Polymerizations and Hydrogel Formation, in the Journal of Visualized Experiments (Jove). The paper discussed one of the main benefits to using poly(ethylene glycol) (PEG) macromers in hydrogel formation is synthetic versatility. The ability to draw from a large variety of PEG molecular weights and configurations (arm number, arm length, and branching pattern) affords researchers tight control over resulting hydrogel structures and properties, including Young's modulus and mesh size.
