Layered Double Hydroxides (LDHs), also known as anionic clays, consist of brucite-like layers with intercalated exchangeable anions and with water molecules; they have extensive applications in environmental, catalytic, industrial and biomedical fields,. These layered solids have been regarded as inorganic drug carriers due to their ability to intercalate biomolecules, particularly negatively charged ones, between the positively charged layers and then to release them on demand.Drug-carrying LDH@iron oxide nanocomposites have been introduced as an alternative to conventional polymer-iron oxide systems for magnetic drug delivery applications. Several magnetic core-LDH shell nanocomposites have been suggested for targeted magnetic drug delivery purposes.
