Two‐photon lithography has been used to create a three‐dimensional metallic structure for the first time. A porous gel filled with AgNO 3 solution was laser irradiated in a multi‐photon process that allowed silver nanocrystals to be written only on the interior of the gel, resulting in the macroscopic three‐ dimensional spiral shown in the Figure.
