Schematic representation of the entire process involved in forming injectable cryogels: (a) the cryogelation procedure of microcomposite cryogels containing CP: (1) Cryogels were manufactured using 4% HAGM with different amounts of CP (0–0.2% CaO₂); an initiator system is added to an aqueous HAGM solution, and then cryopolymerization is performed at $-$20 °C. (2) Ice crystal formation and gelation occurs. With the thawing of the ice crystals, an interconnected macroporous cryogel is formed. (b) dehydrated and hydrated forms of the obtained cryogels, (c) pre- and post-injection cryogel forms from a 16 G hypodermic needle, and (d) cryogels conserve encapsulated CP after injection [69].
