This review focuses on cryogels derived from inorganic nanocrystals, prepared using a simple and versatile method of freezing and freeze-drying an aqueous nanoparticle colloid. We explore how factors like freezing temperature and nanoparticle composition can influence the cryogel structure. We discuss the properties and applications, along with the challenges and future directions for this promising material.
