Silicon-Protein Interfaces
Current fabrication methods allow us to work at macroscopic scales (10^0 m) down to the nanometer scale (10^-8 m) with photolithography, and further down to the atomic scale (10^-10 m) with proteins. However, directly bridging from macroscopic to atomic scales (10^0 m to 10^-10 m) for nanotechnology applications remains a significant challenge. A key obstacle is the lack of effective interfaces between single addressable electrodes and proteins.

Our current methods do not allow precise control over the positional placement of atoms or groups during chemical synthesis, limiting our ability to build molecules with atomic precision. A general-purpose approach to atomically precise fabrication was envisioned by Drexler in the 1980s and Feynman ...
