Hydrogels are a three-dimensional networks of polymer chains swollen with water . Self-assembling peptides can be used to form versatile and tuneable hydrogels with an intrinsic biocompatibility and a range of biomechanical and biophysical properties . This makes them suitable for use in a range of applications such as early stage interventions for musculoskeletal disorders, drug delivery platforms or scaffolds for cell therapies . In order to fully utilise these biomaterials for practical applications, the design principles that drive self-assembly and determine their material properties need to be better understood.
