    Abstract: An injectable hydrogel network is provided distinguishing a non-covalently cross-linked hydrogel network with polymers functionalized with hydrophobic fatty pendant groups hydrophobically cross-linked with liposomal nanoparticles in which the liposomal nanoparticles are the cross-linkers. As the hydrogel is injectable, it is easily administered under the skin and does not require invasive surgical implantation. After injection the hydrogel rapidly self-heals to form a robust solid-like depot that can persist in the body over relevant timescales. The material does not cause a negative immune response like many other materials do. The hydrogel can gradually degrade over time in the body and therefore would not require surgical removal. Different embodiments modifying the surface chemistry of the liposomes give this hydrogel the ability to release therapeutic cargo, such as proteins, over controlled programmable timescales regardless of cargo size because the material can interact with the cargo through electrostatic or affinity interactions.
