a
Mv = viscosity-based molecular weight of azide-appended polymers.
b
Average contour length based on Mv.
c
Polymer concentration.
d
Density of conjugated RGD peptide.
e
Molecular weights of precursor PIC-N3 polymers were measured. The mechanical properties of S1 and S3 have been measured in triplets and show overlapping curves (Figure S1).
