Measuring conductance switching in single proteins using quantum tunneling Open
Interpreting the electrical signatures of single proteins in electronic junctions has facilitated a better understanding of the intrinsic properties of proteins that are fundamental to chemical and biological processes. Often, this informa…

Water evaporation–induced electricity with <i>Geobacter sulfurreducens</i> biofilms Open
Water evaporation–induced electricity generators (WEGs) have recently attracted extensive research attention as an emerging renewable energy–harvesting technology that harvests electricity directly from water evaporation. However, the low …

Electronic Transport in Molecular Wires of Precisely Controlled Length Built from Modular Proteins Open
DNA molecular wires have been studied extensively because of the ease with which molecules of controlled length and composition can be synthesized. The same has not been true for proteins. Here, we have synthesized and studied a series of …

Probing Bioelectronic Connections Using Streptavidin Molecules with Modified Valency Open
As molecular electronic components, proteins are distinguished by a remarkably long electronic decay length (∼10 nm) together with high contact resistance and extreme sensitivity to the chemical details of the contact. As a consequence, th…

Electronic Decay Length in a Protein Molecule Open
Antibodies have two identical binding domains and can therefore form a well-defined conducting bridge by binding a pair of electrodes functionalized with an epitope. The conductance measured between these two fixed points on the antibody d…

Role of contacts in long-range protein conductance Open
Significance The measured electronic properties of proteins are known to depend critically on contacts, although little is known at the single-molecule level. Here, we have measured the conductance of single-protein molecules in their natu…

Observation of giant conductance fluctuations in a protein Open
Proteins are insulating molecular solids, yet even those containing easily reduced or oxidized centers can have single-molecule electronic conductances that are too large to account for with conventional transport theories. Here, we report…
