Sub-10 nm Resolution Patterning of Pockets for Enzyme Immobilization with Independent Density and Quasi-3D Topography Control


Research is led by Elisa Riedo, professor of chemical and biomolecular engineering at NYU Tandon.

The ability to precisely control the localization of enzymes on a surface is critical for several applications including biosensing, bio-nanoreactors, and single molecule studies. Despite recent advances, fabrication of enzyme patterns with resolution at the single enzyme level is limited by the lack of lithography methods that combine high resolution, compatibility with soft, polymeric structures, ease of fabrication, and high throughput. Here, a method to generate enzyme nanopatterns (using thermolysin as a model system) on a polymer surface is demonstrated using thermochemical scanning probe lithography (tc-SPL).
