Figure 1. Overview of gelNOR synthesis and cross-linking reaction, and volumetric photografting process.

Figure 1

A) Synthesis of gelNOR with addition of carbic anhydride at multiple time points. B) Schematic representation of the cross-linking mechanism of gelNOR with a dithiolated cross-linker, showing the two cross-linkers used in this study, DTT and DEG. C) Schematic representation of the volumetric photografting technique including volumetric printing, the infusion strategy with a thiolated compounds, and a second volumetric projection step for volumetric photografting of these compounds into complex structures within a gelNOR construct using covalent thiol–ene chemistry.
