A method for making three-dimensional structures having nanometric and micrometric dimensions

摘要

A method for making three-dimensional structures of nanometric or micrometric dimensions comprises the following steps: obtaining of a photopolymeric or UV mixture (M) including nanoparticles orientable in space; deposition of a layer of the mixture (M) on a respective substrate (30); exposure of the layer (M) to UV-radiation (F1) and control of the polymerization of the mixture by means of variation of its index of refraction; application of a magnetic and/or electrical field for producing a desired positioning of the nanoparticles, in order to induce the growth of surface projections (R) from the layer of mixture (M); and polymerization of the mixture (M).
