Poly‐ N ‐isopropylacrylamide Colloidal Arrays as Templates for Droplet‐Assisted Fabrication of Plasmonic Nanostructure Patterns

Poly-N-isopropylacrylamide colloidal arrays are exploited for site-selective self-assembly of gold nanoparticles on large areas. The soft colloids host the drying process of gold nanoparticle dispersion droplets and leave room for capillary convection and Marangoni convection flow paving the road to a simple bottom-up fabrication strategy for nanostructure arrays.
