Morphological and chemical analyses of the nanotube-modified GelMA-based hydrogels. (a) SEM micrograph of a GelMA hydrogel cross-section. (b) SEM and (c) BSE-SEM micrographs of a cross-section of GelMA modified with CHX-loaded nanotubes (5% H-10% C). Note the presence of the aluminosilicate nanotubes based on the brightest areas throughout the microstructure (⧫). (d) EDS results confirm the presence of Si and Al. (e-h) SEM micrographs combined with BSE-EDS elemental mapping of cross-section GelMA hydrogel modified with CHX-loaded nanotubes show a uniform distribution of the nanotubes within the hydrogel matrix.
