Ultrathin cantilevers based on polymer-ceramic nanocomposite assembled through layer-by-layer adsorption

An ultrathin cantilever based on nanoorganized film from six alternating monolayers of clay plates, polycations, and magnetite nanoparticles was developed. The 170-nm thick clay−polymer−magnetite cantilever is a magnetic free-standing microstrip with a root anchored on a substrate. Hundreds of such cantilevers can be produced on a solid substrate within one processing cycle and, therefore, to provide sensor arrays or an adjustable surface with synchronized cantilever movements using an external magnetic field.
