Building miniature optical antennas using DNA as a guide

Aalto University researchers have developed a new method called DALI (DNA-assisted lithography) to fabricate precise metallic nanostructures with designed plasmonic properties. The technique uses self-assembled DNA origami shapes as 'stencils' to create millions of fully metallic nanostructures. These structures have intriguing optical...
