Possibilities for layered double hydroxides (LDH) nanotubes in biological applications

Luminescent plate-like nano-LDH and nanotubular LDH anion exchangers composite were assembled from inorganic oligo-layered walls LDHs containing rare earth elements. This high-surface area and micro and mesoporous structure facilitates interaction with different species, providing significant potential for hosting sensitizers, dendrimers or nanoparticles. As both the interlayer space and the mesopore are accessible, these materials offers great opportunities for catalysis, sensors and transport of biologically active materials.
