Abstract

original image

A laser fabrication technique for metal nanostructures is developed. Owing to the control of the growth of metal particles by surfactants, the spatial resolution of the technique breaks the classical limitation of the light. Three-dimensional silver nanostructures are experimentally demonstrated (see image).
