Electrical transport along bacterial nanowires from Shewanella oneidensis MR-1 (2010, methodology): “For example, Geobacter nanowires are presumed to be conductive as a result of the amino acid sequence of the type IV pilin subunit, PilA, and, possibly, the tertiary structure of the assembled pilus (7).”

(2006, background): “Surprisingly, under conditions that mimic the BUG system, the electrically conductive pili that are essential for electron transfer to Fe(III) oxides [21] were not required for electron transfer to electrodes [20].”

Biofilm and Nanowire Production Leads to Increased Current in Geobacter sulfurreducens Fuel Cells (2006, background): “Cell-to-cell electron transfer via intertwined pili (16) might establish a “nano power grid” in which the pilus network transfers electrons through the 40- to”
Shewanella oneidensis MR-1 nanowires are outer membrane and periplasmic extensions of the extracellular electron transport components (2014, methodology): “Our direct knowledge of bacterial nanowire conductance is limited to measurements made under ex situ dry conditions using solid-state techniques optimized for inorganic nanomaterials (6, 7, 10, 11), without demonstrating the link between these conductive structures and the respiratory electron trans”
Formation of Cell-Iron-Mineral Aggregates by Phototrophic and Nitrate-Reducing Anaerobic Fe(II)-Oxidizing Bacteria (2009, background): “…electron transfer to the cells in a similar way as described recently for the conductive pili in Fe(III)-reducing microorganisms (Gorby et al. 2005; Reguera et al. 2005): whereas the Fe-reducers putatively use the pili to transport electrons from the cells to the solid-phase electron acceptors…”
