The layer-by-layer (LBL) assembly technique, based on sequential adsorption of oppositely charged compounds, continues to be one of the most popular and well-established methods for formation of multilayer thin films. Wide variety of species available has led to a number of potential research and industrial applications in semiconductors, catalysts, optics, magnetic devices, and sensors. In a recent report, we have presented another potential application with LBL assembly of a biomimetic nanostructured composite from montmorillonite clay nanosheets and (poly(diallylmethyl ammonium chloride (PDDA). The structure, deformation mechanism, and mechanical properties of the material are very similar to those of natural nacre and lamellar bones, thus opening the route for generation of new class of biomedical implantable devices.
