Due to the nanometric diameter of a DNA helix (2 nm), this biological molecule appears as a promising scaffold for metallization and low-cost production of metallic nanowires. Since the very first proof-of-concept published 20 years ago, many efforts have been made to explore new routes enabling thinner DNA-based nanowires, with higher conductivity. In collaboration with another laboratory (LMGP, INP-Grenoble), we wish to design an alternative approach based on Atmospheric Pressure Spatial Atomic Layer Deposition (AP-SALD) for the metallization of DNA. Several metals will be used, with a specific emphasis on Cu and Au. Then, such nanomaterial will be functionalized, and conjugated with biomolecules to take benefit of the huge developed area of such active bio-hybrid architectures. This PhD research project thus aims at synthesizing and characterizing new materials made of tuneable and controllable conducting nanowires. A major goal will be the design of enzymatically-active surfaces, whose applications would be a great interest for the production of more powerful biofuels for instance.
