Shining a light on the hidden structure of gelatin methacryloyl bioinks using small-angle X-ray scattering (SAXS)

Small-angle X-ray scattering is used to unpack the hidden structure of a gelatin methacryloyl (GelMA) biogel. We present insights regarding how the degree of functionalisation, crosslinked polymer conformation, nanoscale mesh size and macroscale mechanical properties are interlinked.
