Figure 4. — Tailored release of GFs and cytokines to skin wounds using composite biomaterials. Hydrogels containing GF or cytokines allow for rapid diffusion into the wound bed upon absorption of wound fluids (left panel). NPs encapsulating GFs or cytokines allow for sustained release coinciding with degradation of the NP (center panel). Hybrid biomaterials consisting of fibers containing GFs or cytokines and NPs encapsulating GFs or cytokines allows for biphasic release following degradation of the fiber then the NP (right panel). NP, nanoparticle. Color images are available online.
