Bionanocomposites materials based on mesoporous anionic clays (Layered Double Hydroxide = LDH) containing drugs (MED), magnetic nanoparticles (LDH-MAG), enzymes (LDH-E), hormones (LDH-H), phytohormones (LDH - F), with applications in (bio)medicine, cosmetics, agriculture, cleaning of the waste waters, etc. Specific studies have conducted in these fields: study of the controlled drug release from LDH-MED; toxicity studies and local/systemic tolerance of clay-drug complex; topical and systemic administration of LDH-MED; preliminary of pharmaco-dynamic efficiency; evaluation of transport capability – magnetic targeting of MAGLDH-MED; redox properties.
