Fig. 1. Synthesis and 1H NMR analysis of MeTro/GelMA-AMP composite hydrogels.

Fig. 1.

Design and photocrosslinking of composite hydrogels. The panel shows a schematic of the proposed reaction for synthesis of (a) MeTro, and (b) GelMA, and (c–d) MeTro-GelMA-AMP; AMP, GelMA, and MeTro were added in a TEA (co-initiator) and VC (co-initiator) solution. Immediately prior to photocrosslinking, Eosin Y (photoinitiator) was introduced into the solution. The solution could be sprayed onto a wound area and exposed to visible light to form an adhesive and elastic antimicrobial hydrogel layer. 1H NMR (500 MHz; D2O) spectra of (e) MeTro prepolymer, (f) GelMA prepolymer, and (g) MeTro/GelMA-AMP hydrogels.
