Direct-write polymer nanolithography in ultra-high vacuum

Direct-write polymer nanolithography in ultra-high vacuum

Polymer nanostructures were directly written onto substrates in ultra-high vacuum. The polymer ink was coated onto atomic force microscope (AFM) probes that could be heated to control the ink viscosity. Then, the ink-coated probes were placed into an ultra-high vacuum (UHV) AFM and used to write polymer nanostructures on surfaces, including surfaces cleaned in UHV. Controlling the writing speed...

Protein nanostructures formed via direct-write dip-pen nanolithography.

We report a tip modification strategy coupled with dip-pen nanolithography for depositing proteins on a surface. This methodology offers patterning capabilities on the scale of 45 nm to many micrometers length. The biorecognition properties of nanofeatures composed of immunoglobulin-gamma (IgG) were confirmed by reacting the array with gold nanoparticles coated with anti-IgG. Furthermore, a two...
