Sub-wavelength metal nanostructure fabrication by parallel dip-pen nanolithography

Jang J-W, Nettikadan S., NanoInk Inc, US

Metal nanostructures in sub-wavelength scale have attracted interests in materials engineering and optics research. Metal nanostructures in sub-wavelength scale have been used as plasmonic diffraction gratings and negative index metamaterials. E-beam lithography has been commonly [...]

Measurement of DPN-Ink Viscosity using an AFM Cantilever

Biswas S., Hirtz M., Lenhert S., Fuchs H., Karlsruhe Institute of Technology, DE

The Dip-Pen Nanolithography (DPN) process uses a chemically coated scanning probe tip (the “pen”) to directly deposit a material (“ink”) with nanometer precision onto a substrate. Several experimental parameters have been observed to influence the [...]

Functional lipid nanostructures fabricated by dip-pen nanolithography

Lenhert S., Florida State University, US

Combining the advantages of the structural, chemical, and lyotropic properties of membrane lipids with the nanostructuring capabilities of dip-pen nanolithograpy (DPN), makes possible creation of semisynthetic functional lipid nanostructures. Two examples of critical dimensions that [...]

Preparation of nanopatterned substrates via Dip-pen Nanolithography for stem cell applications

Oberhansl S., Lagunas A., Martinez E., Jamil H., Samitier J., Institute for Bioengineering of Catalonia, ES

Dip-pen Nanolithography is used to fabricate nanopatterned substrates for stem cell experiments. Factors which are known to play a role in stem cell differentiation are immobilized on these substrates. The highly controlled order, in which [...]

Using Scanning Thermal Microscopy Techniques for In-Situ synthesis of Carbon Nanotubes at “room temperature conditions”

Mukkisa S., Banerjee D., Texas A&M University, US

Carbon Nanotubes (CNT) were synthesized at room temperature conditions on a heated scanning probe without the use of conventional Chemical Vapor Deposition (CVD) apparatus or the process gases. The heated scanning probe is composed of [...]

Dip Pen Nanolithography® of Silver Nanoparticle Inks for Printed Electronics

Parpia M., Tevaarwerk E., Amro N., Wang H.T., Haaheim J., Rozhok S., Levesque T., Nafday O.A., NanoInk, US

Precision nanoscale deposition of biological, organic, and inorganic materials is a fundamental need in nanoscience research. Dip Pen Nanolithography® (DPN®) is an inherently additive, SPM-based technique, capable of producing nanoscale features with high resolution and [...]

Haaheim J., Nafday O., Fragala J., Shile R., Val V., NanoInk, US

We present methods and applications of the commercially available 2D nano PrintArray(TM), which provides massive scalability for dip pen nanolithography. We will discuss current applications and future development.

Lipid Dip-Pen Nanolithography for Functional Biomimetic Membrane Systems

Lenhert S., Forschungszentrum Karlsruhe GmbH, DE

Dip Pen Nanolithography (DPN) is uniquely well suited for the integration of multiple materials (or inks) with both high resolution and high throughput. Phospholipid-based inks are particularly well suited for this purpose for several reasons. [...]

Direct Parallel Patterning of Multiplex DNA and protein arrays

Rozhok S., Amro N., Fragala J., Levesque T., Nelson M., NanoInk Inc, US

Multiplex DNA and protein arrays can be routinely generated on glass or metal-coated substrates via Dip-Pen Nanolithography (DPN) using new commercially available DPN accessories like multiple pen arrays and inkwells.
