Formation of ice crystals during the freezing process can rip living tissue, causing unwanted tissue damage, which is why frostbite can be so dangerous. But freeze-drying could be a boon to health care. For example, a way to store blood at room temperature would be a great cost saving measure, but more than that, it could also allow blood to reach remote, rural areas with ease. Core Dynamics is working on developing a process to safely freeze-dry blood cells. Once perfected, this method could lead to long-term storage of tissue, with a greater level of survival once it is rehydrated."
