NanoInk to mix DPN with DNA

Nov. 18, 2003 — NanoInk Inc. has secured the first award of a two-phase, $1.3 million federal grant to develop its Dip-Pen Nanolithography for ultraminiaturization of DNA arrays.

The first phase of the Small Business Innovation Research (SBIR) grant from the National Institutes of Health, worth $100,000, will help the Chicago-based company fabricate and study biomolecule arrays, as well as develop the next generation of the devices for point-of-care diagnostics and biodefense.

The newly patented DPN process is used for building patterns, layers and structures with nearly any molecule at resolutions fewer than 15 nanometers. NanoInk said the process could lead to biomolecule nanoarrays with features up to 10,000 times smaller than conventional microarray technology.
