The process involves decorating a surface with an ordered array of metal nanoparticles produced by means of a micellar block- copolymer nano-lithography process; etching the primary substrate to a depth of 50 to 500 nm, where the nanoparticles act as a mask and an ordered array of nanopillars or nanocones corresponding to the positions of the nanoparticles is thus produced; using the nanostructured master or stamp in a structuring processes. Also the finished nanostructured substrate surface can be used as a sacrificial master which is coated with a continuous metal layer and the master is then etched away to leave a metal stamp having an ordered array of nanoholes which is a negative of the original array of nanopillars or nanocones.
