  • Polyacrylamide - an overview | ScienceDirect Topics

    Polyacrylamide. Polyacrylamides are useful hydrogels that have induced regeneration of soft tissue in facial defects (von Buelow et al., 2005), and 2-hydroxyethyl methacrylate recently has been used as a fibrillar support for nerve regeneration (Flynn et al., 2003). From: Principles of Regenerative Medicine, 2008. Related terms: Antibody; Enzyme; Protein; pH; DNA

That polyacrylamide hydrogel is cut-insensitive was noted in a previous paper focused on elastomers (Chen et al., 2017). It was also noted that this “certain length” is much larger than the mesh size of the hydrogel.
