3-Dimensional Microphysiological Tissue Models

by / Tuesday,12 December 2017

We can tune the viscosity of the hydrogel before it is crosslinked by introducing nanoclay into it. By doing that, the gel exhibits shear thinning effect, it becomes much viscous at low shear rate and less viscous when the shear rate is high. This allows the gel to be 3d printed into shapes like ear and nose, while maintaining the original mechanical prop. The 3d printing fabrication tech allows the gel to be produced in various macroscale structure starting with microscale faber.

This is a video showing the gel maintains its shape even after severe deformation. Jelly This shows the gel has high stretchability as well as compressibility
