Schematic illustrations of the biocompatibility of PU nanocomposites. (A) NMs induce osteogenesis for the regeneration of hard tissue. (B) NMs promote wound healing by increasing oxygen transmission and excreting metabolites. (C) Conductive NM/PU fibers provide an electrophysiological environment and induce directed migration to accelerate peripheral nerve repair. (D) PU nanocomposites promote surface endothelialization by releasing bioactive NMs.
