The present invention refers to the obtention of nanorods and nanothreads of CuO by the aerosol assisted chemical vapor deposition method (AACVD) in a relatively easy and simple manner to be reproduced at an affordable cost, using a solution of an alcoholic or aqueous solvent and a copper salt. This solution is nebulized and transported to a substrate that has a coating of metallic oxide in the surface thereof, which is arranged in an oven at a temperature ranging from 350°C to 900°C, generating nanorods and nanothreads of CuO. Layers of other materials may be subsequently deposited for uniformly coating the nanostructures. Esta invención se refiere a la obtención de nanovarillas y nanohilos de CuO por el método de depósito químico de vapor asistido por aerosol (AACVD por sus siglas en inglés) de una manera relativamente sencilla y fácil de reproducir, además de bajo costo, utilizando una solución de un solvente alcohólico o acuoso y una sal de cobre. Esta solución se nebuliza y es transportada hacia un substrato que tiene una capa de óxido metálico en su superficie, y se encuentra colocado en un horno a una temperatura entre 350 y 900 °C generando nanovarillas y nanohilos de CuO. Posteriormente se pueden depositar capas de otros materiales para recubrir uniformemente las nanoestructuras.
