Gallate-Zn-Al-layered double hydroxide as an intercalated compound with new controlled release formulation of anticarcinogenic agent.

A new organic-clay material, in which the organic moiety is intercalated into the inorganic interlayer, was prepared using gallate anion (GA) as a guest, and Zn–Al-layered double hydroxide, as clay host. The ion-exchange technique was found to be effective for the intercalation process in the format...
