Fig. 7 — Fabrication of MeTro/GO/GelMA hybrid platforms. (a) Demonstrative pictures showing highly elastic MeTro/GO made using GO (1 mg/ml) and MeTro prepolymer solution (10%) before and after the stretching. (b) Shows MeTro molecules with an irregular coil and a C-terminal cell interactive groups (c) Shows the binding of GO with MeTro utilizing hydrophobic interactions. The figure also shows representative (d) HRTEM images of dispersed GO and (e) MeTro bound GO particles, representing tropoelastin ﬁber covering over GO particles. (f) SEM images of highly interconnected MeTro/GO hydrogel network (g) Representation of MeTro hydrogel network formed by photopolymerization. (h) Formation of covalently conjugated MeTro/GO hydrogel employing UV irradiation and physical interaction between GO particles and MeTro molecules. Reproduced with permission from Ref.
