NanoInk's NanoFabrication Systems Division has introduced its next generation Dip Pen Nanolithography (DPN) system for desktop nanofabrication, the DPN 5000. This instrument brings greater control and performance to the world of desktop nanofabrication.
The DPN 5000 offers versatile nanopatterning capabilities coupled with high-performance AFM (atomic force microscopy) imaging for immediate characterization of the deposited patterns. NanoInk has developed a variety of custom MEMS (micro electromechanical systems) based ink delivery devices, allowing a range of materials to be deposited under precisely controlled conditions.
System highlights include a new, ultra-low noise scanner with closed-loop flexure technology to produce accurate and repeatable nanoscale patterns. For subsequent imaging of substrates, a low coherence laser with a reduced laser spot size assures high quality lateral force imaging. In addition, NanoInk's enhanced lithography software, InkCAD 4.0, includes improved control of tip-based patterning, along with nanoscale mapping and positioning, allowing users to precisely position multiple features even when created from different materials.
The DPN 5000 comes fully equipped with a range of enabling MEMS based ink delivery consumable items. Manufactured in NanoInk's MEMS facility, these DPN patterning tools include single probes, 1D passive probe arrays, individually actuated Active Pen Arrays, 2D probe arrays with up to 55,000 pens (2D nano PrintArray), inkwells for coating tips and substrates to be written upon. These devices allow researchers to rapidly create nanostructures using numerous materials including proteins, DNA, nanoparticles and polymers.
