In the present study, low-temperature heating of the dry residue of a 10 µL droplet of an HAuCl4 solution on a substrate and a metallic foil facing the dry residue was performed for 20 min in air in order to produce gold nanostructures on the metallic foil. When a titanium foil and a stainless steel...
