A method is provided for preparing porous nanostructured ceramic bilayers resting on a substrate, to the bilayers obtained by the method, and to the various uses of same, in particular in micro and nanofluidics, optics, photocatalysis and for separating and detecting analytes or molecules of interest. The method includes: 1) a first step of forming a supported polymer cavity having oriented cylindrical porosity; 2) a second step of filling and covering the polymer cavity with a solution or a dispersion of at least one ceramic precursor, optionally functionalised, in an organic solvent; 3) a third step of eliminating the polymer cavity used in step 2) by thermal treatment.
