New Extended Variable Temperature Control Module to Enhance DPN

Published on May 28, 2009 at 7:34 PM

Recent advances in producing a variety of new nanoscale products using NanoInk's patented Dip Pen Nanolithography(R) (DPN(R)) have been achieved with a new thermoelectric variable temperature stage module. Vice President of NanoInk's NanoFabrication System Division, Tom Levesque stated "We have seen that the versatility of the materials which can be controllably deposited with DPN will grow with this new range of temperatures. Previous work centered around materials deposited close to ambient conditions, but this new approach enables the deposition of a wide variety of new molecules that were deemed challenging and impossible to deposit under ambient conditions. This gives us more flexibility and expands our choice of chemistries. This new stage extends the range from as low as 4 to as high as 80 degrees C."

Recent work presented at the NSTI meeting in Houston, Texas, showed how extended temperatures enabled the creation of modified substrates for stem cell culture. Dr. Nabil A. Amro, Senior Scientist at NanoInk, explained: "Our ability to fabricate features of alkanethiols under 100nm in size and extending over areas of square centimeters could not have been achieved without extended temperature control. These substrates are proving truly remarkable at controlling and selecting specific stem cell paths of differentiation."

The extended temperature DPN module will be available for NanoInk's DPN 5000 and NSCRIPTOR(R) systems in July. Contact NanoInk for more information at
