Table 1.
Composition of collagen gel samples and comparison of the storage and loss moduli recorded at 1.6 Hz. Ccoll lists the actual concentration of collagen in the sample, while CTPAu represents the actual concentration of nanoparticles in the sample. Mass ratio refers to ratio of masses of dry collagen to dry TPAu without solvent.
