Abstract

A new lithography technique is presented that exploits the interactions of immiscible liquids with a structured surface. This highly parallel, “low-tech” method requires no dedicated equipment and easily produces curved and/or multi-level structures out of a variety of photoactive and non-photoactive materials.
