Fabrication of nano-patterns composed by metal nanoparticles with photo-nanoimprint

Nanopatterns of alkanethiol-capped gold nanoparticles are fabricated on photocurable polymer surface using a photo-nanoimprint method. The surface morphology of the nanopattern is observed by scanning electron microscopy and transmission electron microscopy. Spherical gold nanoparticles with a 3.5 nm average diameter and 500 nm line width is obtained.
