Off-resonant coherent electron transport over three nanometers in multi-heme protein bioelectronic junctions
Zdenek Futera, Ichiro Ide, Ben Kayser +9
Multi-heme cytochromes (MHC) are fascinating proteins used by bacterial organisms to shuttle electrons within and between their cells. When placed in a solid state electronic junct…
Protein bioelectronics: a review of what we do and do not know
Christopher D. Bostick, Sabyasachi Mukhopadhyay, Israel Pecht +3
We review the status of protein-based molecular electronics. First we discuss fundamental concepts of electron transfer and transport in and across proteins and proposed mechanisms…
Doping Human Serum Albumin with Retinoate Markedly Enhances Electron Transport Across the Protein
Nadav Amdursky, Israel Pecht, Mordechai Sheves +1
Electrons can migrate via proteins over distances that are considered long for non-conjugated systems. Proteins' nano-scale dimensions and the enormous flexibility of their structu…
Marked changes in electron transport through the blue copper protein azurin in the solid state upon deuteration
Nadav Amdursky, Israel Pecht, Mordechai Sheves +1
Measuring electron transport (ETp) across proteins in the solid-state offers a way to study electron transfer (ET) mechanism(s) that minimizes solvation effects on the process. Sol…
Temperature and force dependence of nanoscale electron transport via the Cu protein Azurin
Wenjie Li, Lior Sepunaru, Nadav Amdursky +4
The mechanisms of solid-state electron transport (ETp) via a monolayer of immobilized Azurin (Az) was examined by conducting probe atomic force microscopy (CP-AFM), both as functio…
