Fig. 1.

Schematic illustrating the two-stage process of peptide gel fabrication, along with the degrees of freedom achievable in design. (a) The initial formation of a cell- and matrix-free precursor allows subsequent functionalisation by physically mixing in matrix components of interest. (b) Quantification of the increase in complex viscosity between the precursor and the final 6 mg/mL peptide gel, measured by microrheology and bulk oscillatory rheology. Trendlines of data collected from 5 replicates are shown along with 95% confidence intervals (red).
