The movement of electrons across wires is what allows us to use electricity every day. Biological nanowires—microscopic wires made of proteins—have caught researchers’ attention for their ability to carry electrons over long distances. In a recent study published in the journal Small by the Josh Vermaas lab in the Michigan State University-Department of Energy Plant Research Laboratory, researchers expand our understanding of biological nanowires through the use of computer simulations. Understanding how these nanowires can be constructed to allow for more electron flow is crucial to future endeavors using them to connect biological processes to conventional electronics.
