Gel-NVs-based bioinks for bioprinting and microfabrication. (A) Schematic representation of the bioprinting process. Created with BioRender.com. (B) 3D printed patches (i) and spirals (ii) with different concentrations of fluorescein-loaded hELs. Average fiber diameter of 3D printed (C) patches and (D) spirals with different concentrations of fluorescein-loaded hELs (n=12). (E) (i) Free-standing and mechanically robust 3D printed patch and (ii-iv) complex shapes using Gel-NVs-based loaded with pink food dye (pink) or fluorescein-loaded hELs. (F) Live/dead image and (G) quantified viability of 3D bioprinted construct with CF-laden Gel-hEL bioink at day 3 (n=9). (H) Schematic representation of the photolithography microfabrication process. Created with BioRender.com. (I) Fluorescence images of microfabricated various blocks with PKH67-labeled NVs encapsulated GelMA bioink. All data are expressed as mean ± standard deviation. Significance is indicated as **(p < 0.01) and ***(p < 0.001).
