"We are very proud that NanoInk is releasing its first product and is revenue generating after only seven months of operation," said Chris Anzalone, chief executive officer of NanoInk. "There is a market demand for our product."

The dip pen nanolithography technique uses the tip of an atomic force microscope to deposit molecules onto a surface. NanoInk says that the technology can deposit virtually any molecule onto virtually any surface.

NanoInk claims that the DPN System 1 is currently the only tool that combines such material flexibility with the ability to build features as small as 10 nm. The system incorporates a computer-aided-design software package.

NanoInk was founded in 2001 by Chad Mirkin, a professor at Northwestern University. The firm has its headquarters in Chicago, US.
