Popis: The use of two-photon 3D printing to create templates for fabricating reproducible and tunable metallic nanostructures is described. The approach allows the structure of the template to be designed specifically for particular applications, e.g., fluid flow control, surface enhanced Raman spectroscopy, metal enhanced fluorescence etc. Here, we show that this method offers excellent control of the size, pitch and packing of spheres on both conducting and insulating substrates, unlike nanosphere lithography. Gold is deposited through these templates and the template then removed using a plasma etching method. In this way, gold nanotriangles, nanodiamonds and nanocavities have been created and characterized using SEM to determine the accuracy of the structures compared to the software designs.
