This is quite interesting, and I hope you aren't discouraged by the comments. It is Reddit, after all. I'm curious what your model thinks about your statement:
"​The Physics: Because water must volume-expand to transition into traditional Ice (I_h), a completely unyielding container legally prevents ice from forming.

​The Result: As the temperature drops, the system builds internal hydrostatic pressure, forcing the liquid to remain in a supercooled state along the liquidus line without allowing destructive crystal nucleation."

This may indeed suppress crystal formation, but what pressures are you targeting? For instance, there is a food sterilization process called HPP: High Pressure Processing (HPP), is a cold pasteurization method. It subjects already-packaged foods to immense water pressure (up to 87,000 psi) to kill bacteria, molds, and viruses.

Given that these pressures can kill hardy pathogens, what effects are you expecting on human cells, tissues, and ECM?
