Creation of Protein Nanoarrays using Dip-Pen Nanolithography

Thompson D.G., McKenna E., Pitt A., Graham D., University of Strathclyde, UK

This presentation describes the creation of protein nanoarrays on a nitrocellulose surface using Dip-Pen Nanolithography and their use in studying protein:protein interactions in an assay format.

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 [...]

Nanolithographic Patterning of Catalysts for Synthesis of Carbon Nanotubes

Gargate R.V., Banerjee D., Texas A&M University, US

Carbon nanotubes (CNT) were synthesized on specially custom designed MEMS chips under ambient conditions without requiring conventional Chemical vapor deposition(CVD) apparatus or process gases. In this approach, a layer of fullerene (C60) of 200 nm [...]

Commercially Available High-Throughput Dip Pen Nanolithography®

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.

Fabrication of biosensor arrays by DPN and multiple target detection by triple wavelength fast SERRS mapping

Stokes R.J., Dougan J.A., Stevenson R., Haaheim J., Levesque T., Faulds K., Graham D., University of Strathclyde, UK

We have used Dip-Pen Nanolithography (DPN) to create biosensor arrays on micro- and nano-structured surfaces. Bespoke linker and labelling materials enables detection of biological molecules by surface enhanced resonance Raman scattering (SERRS). Careful DPN-directed placement [...]

Dip Pen Nanolithography®: A Maturing Technology for High-Throughput Flexible Nanopatterning

Haaheim J.R., Tevaarwerk E.R., Fragala J., Shile R., NanoInk Inc, US

Precision nanoscale deposition is a fundamental requirement for much of current nanoscience research. Further, depositing a wide range of materials as nanoscale features onto diverse surfaces is a challenging requirement for nanoscale processing systems. As [...]

Haaheim J., NanoInk Inc, US

Precision nanoscale deposition is a fundamental requirement for much of current nanoscience research. Further, depositing a wide range of materials as nanoscale features onto diverse surfaces is a challenging requirement for nanoscale processing systems. Dip [...]

Investigation of Volume of Fluids (VOF) Method and System Models for Design of Microfluidic Ink Delivery Apparatus for Dip Pen Nanolithography (DPN)

Banerjee D., Texas A&M University, US

DPN™ is a versatile technology that leverages Scanning Probe Microscopy for applications in biotechnology, photomask repair, molecular-electronics, nano-electronics and mask-less lithography(1). In earlier studies (2) the DPN process was augmented for biotechnology applications (genomics, proteomics) [...]
