Hydrogel
Hydrogel — A three-dimensional polymer network capable of absorbing large amounts of water, used as a matrix for peptide delivery and tissue engineering.
What Is a Hydrogel?
A hydrogel is a three-dimensional network of hydrophilic polymers or peptides that absorbs and retains large amounts of water while maintaining structural integrity. In peptide research, self-assembling peptide hydrogels serve as injectable depot formulations, tissue engineering scaffolds, and controlled-release drug delivery matrices.
Self-Assembling Peptide Hydrogels
- RADA16: Ionic-complementary peptide forming nanofibrous hydrogels at physiological pH. FDA-cleared as hemostatic agent (PuraStat)
- MAX1/MAX8: Beta-hairpin peptides that undergo shear-thinning (injectable) and rapid recovery (gelling in tissue)
- Fmoc-dipeptides: Ultra-short peptides (Fmoc-FF, Fmoc-RGD) that self-assemble into hydrogels through aromatic stacking
