[News Feed] Innovative Fountain Pen Writes On The Nanoscale

[Forum Mouse]

The first practical fountain pen was invented in 1884 by Lewis Waterman who solved the problem of ink leaks by inventing the capillary feed which produced even ink flow. Now fountain pen history is repeating itself in the world of nanoscale writing. Northwestern University researchers have developed an atomic force microscope probe chip with an integrated microfluidic system for capillary feeding of molecular ink and have demonstrated writing at the sub-100 nanometer scale in fountain-pen fashion.
