Abstract

Nanostructuring at the Leidenfrost temperature is carried out by exposing water-based solution droplets to overheated substrates at temperatures above 200 °C. This method is able to produce nanowires that form different geometries (see figure and inside cover) by inverting the Lotus effect: instead of removing material, moving droplets deposit nanoparticles. Alignment is achieved by employing simple masks.
