The World’s Smallest Fountain Pen? 1
The miniscule tip on an atomic-force microscope (AFM) helps researchers both "see" and manipulate the nanoscale environment. Now, engineers have created two novel technologies that enable such tips to write features as small as viruses and to withstand abuse with the resilience of diamond. Eventually, they believe, vast arrays of such nanofountain probes could prove useful for crafting such intricate systems as protein arrays or complex semiconductors.
