Although proteins are considered as nonconductors that transfer electrons only up to 1 to 2 nanometers via tunneling, Geobacter sulfurreducens transports respiratory electrons over micrometers, to insoluble acceptors or syntrophic partner cells, via

Multifunctional living materials are attractive due to their powerful ability to self-repair and replicate. However, most natural materials lack electronic functionality. Here we show that an electric field, applied to electricity-producing Geobacter

Terahertz-Conductivity in Biological Nanowire-Networks

Autor: Vishok Srikanth, Charles A. Schmuttenmaer, J. Patrick O'Brien, Sophia M. Yi, Nikhil S. Malvankar, Dennis Vu, Yangqi Gu, Jens Neu

Publikováno v: 2019 44th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz).

Most proteins are electrical insulators or poor conductors. We present temperature resolved conductivity measurements on electrically conducting proteins. Temperature-resolved THz spectroscopy was used as a contact free method to measure the conducti

A Simple and Low‐Cost Procedure for Growing Geobacter sulfurreducens Cell Cultures and Biofilms in Bioelectrochemical Systems

Autor: J. Patrick O'Brien, Nikhil S. Malvankar

Publikováno v: Current Protocols in Microbiology

Anaerobic microorganisms play a central role in several environmental processes and regulate global biogeochemical cycling of nutrients and minerals. Many anaerobic microorganisms are important for the production of bioenergy and biofuels. However, t
