Characterization of the GelMA and GelMA–MWCNTs/Co hydrogels. (A) SEM images of GelMA and GelMA–MWCNTs/Co hydrogels. (B) EDX elemental mapping of GelMA and GelMA–MWCNTs/Co (C: Carbon, N: Nitrogen, O: Oxygen, Co: Cobalt). (C) Release of Co ions from the bare MWCNTs/Co and GelMA–MWCNTs/Co hydrogels in the medium. (D) Storage modulus (G′) and loss modulus (G″), (E) Compressive stress-strain curves, and (F) In vitro degradation ratio of GelMA and GelMA–MWCNTs/Co hydrogels (n = 4)
