Clay minerals are relevant materials for any industrial application for preparation of new materilas in nanoscience and nanotechnology. Self-assembled layered materials can be used for thin film preparation and also for nanohybrid systems. Polyelectrolytes and polymers show strong interaction with clay minerals and layer double hydroxides. The knowledge on surface biofunctionalisation with different biopolymers, like peptides and proteins could be very useful for preparation of polymer nanocomposite materials for industrial and pharmaceutical application.
