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 [...]

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 [...]

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.
