Acrylamide-PEG-Acrylamide (ACA-PEG-ACA)

Price range: $300.00 through $1,200.00

Acrylamide-PEG-Acrylamide (ACA-PEG-ACA) is a linear difunctional polyethylene glycol (PEG) derivative terminated with acrylamide groups at both ends. The acrylamide functionalities undergo free-radical polymerization and Michael-type reactions with thiol-containing molecules, making ACA-PEG-ACA an excellent macromolecular crosslinker for hydrogel formation, tissue engineering, drug delivery, and biomaterials research.

ACA-PEG-ACA

Description

General Description

Acrylamide-PEG-Acrylamide (ACA-PEG-ACA) is a bifunctional PEG crosslinker designed for the fabrication of hydrophilic polymer networks and biocompatible hydrogels. The central PEG spacer provides excellent water solubility, flexibility, and biocompatibility, while the terminal acrylamide groups participate in radical polymerization or thiol-Michael addition to form stable three-dimensional polymer networks.

ACA-PEG-ACA is widely used to prepare PEG-based hydrogels with tunable mechanical properties, swelling behavior, and degradation profiles. These hydrogels are extensively employed in drug delivery, cell encapsulation, tissue engineering, bioinks for 3D bioprinting, biosensors, wound healing, and regenerative medicine.

Compared with conventional small-molecule crosslinkers, ACA-PEG-ACA offers improved flexibility, reduced cytotoxicity, and enhanced control over network architecture, making it a preferred material for biomedical and pharmaceutical applications.
