General Description
8-Arm PEG-Acrylate is a multifunctional PEG crosslinker designed for the preparation of highly crosslinked hydrogel networks and advanced biomaterials. The eight-arm architecture provides a high density of reactive acrylate groups, resulting in rapid gelation, increased crosslinking efficiency, and improved mechanical strength compared with linear or four-arm PEG derivatives.
The terminal acrylate groups readily react with thiol-containing molecules through Michael addition or undergo free-radical polymerization initiated by thermal or photochemical initiators. This versatility makes 8-Arm PEG-Acrylate suitable for fabricating injectable hydrogels, photocurable bioinks, drug delivery matrices, tissue engineering scaffolds, and cell encapsulation systems.
The PEG backbone provides excellent water solubility, flexibility, biocompatibility, and resistance to nonspecific protein adsorption. 8-Arm PEG-Acrylate is widely used in regenerative medicine, three-dimensional cell culture, biofabrication, wound healing, and controlled drug release applications.
