• Most conventional lithography uses a variety of techniques to focus light on a photosensitive film to create 2-D patterns - They rely on specialized lenses, electron beams or lasers - all of which are extremely expensive
  • The researchers took a different approach, placing nanoscale polystyrene spheres on the surface of the photosensitive film
  • The new technique could also be used to create nanoscale "inkjet printers" for printing electronics or biological cells, or to create antennas or photonic components.
