This particular article is referring to cryogels, not cryogenics, although I can’t say I haven’t made the same mistake in the past. Cryogels are much like aerogels in that they are an air-pocketed foam-like substance, but cryogels are made by a different process (freeze drying). If I understand correctly, the cells aren’t being put into any form of sleep at all, merely being preserved and fed within the gel.
