Nanotechnology-Based Therapies for Skin Wound Regeneration

Figure 2

Nanostrategies currently in use for promoting skin wound healing. In the main panel, nanostrategies currently in use to improve healing are illustrated. The therapeutic potential of nanosphere-based strategies and nanoscaffolds is emphasized through correlation with the healing phase to which the biological action is targeted. In the right panel, materials explored for nanoparticulate-delivery systems are listed. Two- and three-dimensional nanofibrous sheets can be made of both degradable (collagen and chitosan) and nondegradable (PLA, PLACL, polyurethane, and PVA polymers) nanofibers.
