Light‐Directed Assembly of Nanoparticles

Abstract

How can patterned thin films of nanocrystals be self-assembled? This contribution describes a general strategy that combines biochemical and lithographic techniques to restrict the assembly of nanocrystals to parts of a surface previously exposed to UV/Vis irradiation. The scanning electron microscope image on the right shows a pattern of gold nanoparticles assembled on a silicon substrate.
