Nanocomposite hydrogels from CNTs and GelMA. a: Schematic showing synthesis of nanocomposite network. First, CNTs are coated with GelMA and then the composite is subjected to UV radiation to obtain photocrosslinked network. b: Due to photocrosslinking ability of the nanocomposite network, microfabrication technologies can be used to control cellular interactions. c: Cardiac cells that were seeded on CNTs-GelMA nanocomposites retained their phenotype as determined by the expression of sarcomeric α-actinin and troponin I. d: The engineered cardiac patch obtained by seeding cardiac cells on CNTs-GelMA surface showed macroscopic mechanical displacement due to continuous contraction and relaxation of the patch.
