Despite decades of effort, current structural, electronic, and optical materials remain fundamentally bioincompatible. Synthetic conducting polymers are typically stiff and brittle, as well as non-biodegradable, and show poor stability and performance due to disorder. We aim to leverage the unique ability of bacterial systems to synthesize electronic materials with high conductivity and ability to self-repair and replicate. Electrogenetics has potential to efficiently control bacterial growth, adhesion, and communication. We have found that electric fields can directly control bacterial synthesis of nanowires made up of cytochromes OmcS (Cell 2019) and OmcZ (Nature Chem.Bio. 2020) without any mediators. We have further found that the nanowires are translocated to the bacterial surface using pili that serve as a piston to secrete cytochromes rather than functioning as nanowires as previously thought.
