Description
Nanostructures and nanoparticles have garnered increasing interest over the past decade due to their unique properties and applications. These properties include localized surface plasmon resonance (LSPR) and allow for surface modification. We can tune these properties depending on the nanoparticle’s size, shape, and geometry.
This work aims to fabricate plasmonic platforms through patterning gold nanoparticles (raspberries) by microcontact printing, a simple and cost-effective soft lithography technique. This is done through large-scale patterning using polydimethylsiloxane (PDMS) stamps to pattern an adhesion template and spatially guide the adsorption of gold nanoparticles (AuNPs).
