A DNA-Based 3D Nanofabrication for Surface Engineering

Abstract

The goal of this project is to develop a general approach to fabricate nanoscale 3D textured surfaces using 3D DNA nanostructure templates. With a coating of 3D nanostructure, a surface can exhibit favorable interfacial properties, such as super-hydrophobicity, anti-fouling, and dragreduction. However, current approaches to produce such 3D nanostructures require multistep nanofabrication and often specific substrates (e.g., silicon). The proposed approach will produce complex 3D nanoscale patterns on surfaces in a single step and will be of low cost and scalable tolarge areas (> m2). Due to COVID-related disruptions, the project objective has since been slightly modified to include a broader range of DNA-based patterning techinques and their applications in surface engineering.
