Application

Polyethylene glycols (PEGs) are FDA approved hydrophilic polymers. They are non-toxic, non-immunogenic and non-antigenic, and are widely used in a variety of biomedical applications such as bioconjugation, drug delivery, surface functionalization, and tissue engineering. 4arm-PEG2K-Acrylate is a four-arm PEG with acrylate end functional groups on each arm. 4arm-PEG2K-Acrylate has applications in PEG hydrogels for drug delivery, 3D bioprinting and tissue engineering.
