May 11, 2004 – NanoInk Inc. has enhanced its NScriptor DPN Writer system to expand the use of its Dip Pen Nanolithography by writing multiple nanoscale patterns simultaneously, according to a news release.

New systems include passive multi-probe arrays that move in unison in three directions while scanning and writing. The system now can function as a rapid prototyping tool for nanomaterials discovery. The NScriptor also has incorporated Inkwell arrays for coating probes with molecular ink. Microfabricated arrays of microwells are fed solutions of ink via microchannels connected to reservoirs. The reservoirs permit dispensing from NanoInk’s Ink Dispensing Kit, the release said.

The Chicago-based company said the upgraded system is designed to help researchers perform bottom-up fabrication tasks. The DPN process is used for building patterns, layers and structures with nearly any molecule at resolutions fewer than 15 nanometers.
