Injectable Hydrogel versus Plastically Compressed Collagen Scaffold for Central Nervous System Applications

Figure 1

Rheometry frequency sweep for gelled collagen-genipin hydrogels in oscillatory mode (a) and gelled collagen hydrogels in oscillatory mode (b). It is illustrated that drops, so those hydrogels are viscoelastic materials. so this regards a well-structured (gelled) system. We can also see that and are almost independent of frequency so, in general, sedimentation is unlikely to occur and particles are strongly associated. of collagen-genipin hydrogels > of collagen hydrogels and of collagen-genipin hydrogels < of collagen hydrogels.
