Editing Microprinting (section)

==Microstructures==
Using gold [[nanoparticle]] inks on a glass substrate, scientists concluded that it was possible for them to control the production of print patterns to a scale of 2 microns.  After printing, the nano-particle ink suspension was heated using a [[Gaussian beam|Gaussian laser]]; as it heated, the glass would expand due to the [[thermal conductivity]] of the gold nano-ink.  In further experiments, they were able to fuse the nano-particles together into a tighter formation a continuous conductive line.  Such experiments did not directly include font characters but could translate to such usage.<ref name=nano>{{cite thesis|type=Ph.D.|degree=D.Sc.|date=2004|url=http://e-collection.library.ethz.ch/eserv/eth:27519/eth-27519-02.pdf|title=Transport Phenomena in the microprinting and laser annealing of Gold Nanoparticle Inks|publisher=Swiss Federal Institute of Technology|location=Zurich, Switzerland|first1=Nicole Renée|last1=Bieri|page=167<!--appears as page 201 in the digital pdf, marked as page 167 on the page -->|access-date=2015-10-05}}</ref>
