Manipulating the Morphology of Silver Nanoparticles with Local Plasmon-Mediated Control

Abstract

The local morphology of silver nanoparticle films on polydimethylsiloxane can be continuously tuned by illumination and subsequent exposure to water. Illumination causes a plasmon-mediated increase of adhesion. The lower the adhesion, the more water “development” increases the film coalescence. Therefore, a photolithography-like resist-free process is found that allows controlling silver nanoparticles.
