Solar-Driven Microbial Photoelectrochemical Cells with a Nanowire Photocathode

Nano Letters, 2010
We report a self-biased, solar-driven microbial photoelectrochemical cell (solar MPC) that can produce sustainable energy through coupling the microbial catalysis of biodegradable organic matter with solar energy conversion. The solar MPC consists of a p-type cuprous oxide nanowire-arrayed photocathode and an electricigen (Shewanella oneidensis MR-1 ...

Tunable metallic-like conductivity in microbial nanowire networks

Nature Nanotechnology, 2011
Electronic nanostructures made from natural amino acids are attractive because of their relatively low cost, facile processing and absence of toxicity. However, most materials derived from natural amino acids are electronically insulating. Here, we report metallic-like conductivity in films of the bacterium Geobacter sulfurreducens and also in pilin ...

Decorating the Outer Surface of Microbially Produced Protein Nanowires with Peptides

ACS Synthetic Biology, 2019
The potential applications of electrically conductive protein nanowires (e-PNs) harvested from Geobacter sulfurreducens might be greatly expanded if the outer surface of the wires could be modified to confer novel sensing capabilities or to enhance binding to other materials. We developed a simple strategy for functionalizing e-PNs with surface-exposed

Microbial Extension Cords: Nanowires in Shewanella oneidensis

Microbe Magazine, 2015
As part of respiration in microbial and other cells, electrons transfer through an electron transport chain to produce energy as adenosine triphosphate (ATP). For most bacteria, the final electron acceptor is a soluble substrate such as oxygen, sulfate, or nitrate that can be brought into the cell and then reduced.

Conductive Composite Materials Fabricated from Microbially Produced Protein Nanowires

Small, 2018
AbstractProtein‐based electronic materials have numerous potential advantages with respect to sustainability and biocompatibility over electronic materials that are synthesized using harsh chemical processes and/or which contain toxic components. The microorganism Geobacter sulfurreducens synthesizes electrically conductive protein nanowires (e‐PNs ...

Study of Charge Transport Mechanism in Microbial Nanowires

2016
This paper presents the findings from two studies. The first study examined the individual and school level factors associated with the risk of suspension for specific groups of students. Results indicated that gender, race, and disability status were individual factors associated with an increased risk of suspension. Multiple school level factors were

Microbial Energy on the Dark Side Juxtaposed to Nanowire Crosstalk

Microbe Magazine, 2008
In terms of energy exchange, intercellular cross talk, and biochemical inventiveness, the microbial world continues to furnish surprises. Eventually, some of that microbial mystique might provide us sluggish humans with novel approaches for harnessing energy. Meanwhile, probing provides insights as to how microorganisms function under unusual — and, in
