Schematic representation of HPG functionalization and hydrogel fabrication. HPGs are functionalized with multiple methacrylate and alkyne groups. Copolymerization with PEGDA leads to a unique network structure that features local increases in crosslinking density due to the particular properties of HPGs. (1) HPGMA, (2) PEGDA, (3) HPGMA + PEGDA hydrogels.
