Bacteria Will Be Used to Make Computers in Future

To be able to create new and more efficient computer systems, medical devices, and different advanced technologies, researchers are turning to nanomaterials: supplies manipulated on the size of atoms or molecules that exhibit distinctive properties.

Graphene — a flake of carbon as thin as a single later of atoms — is a revolutionary nanomaterial as a consequence of its potential to simply conduct electricity, in addition to its extraordinary mechanical power and suppleness. Nonetheless, a significant hurdle in adopting it for on a regular basis functions is producing graphene at a big scale, whereas however retaining its wonderful properties.

In a paper printed within the journal ChemOpen, Anne S. Meyer, an affiliate professor of biology on the University of Rochester, and her colleagues at Delft University of Technology within the Netherlands describe an option to overcome this barrier. The researchers define their methodology to provide graphene supplies utilizing a novel approach: mixing oxidized graphite with bacteria. Their methodology is a more value-efficient, time-saving, and environmentally pleasant approach of manufacturing graphene supplies versus these produced chemically, and will result in the creation of modern computer technologies and medical gear.

Graphene is extracted from graphite, the fabric present in an extraordinary pencil. At precisely one atom thick, graphene is the thinnest — but most durable — two-dimensional materials recognized to researchers. Researchers from the Manchester University in the United Kingdom had been awarded the 2010 Nobel Prize in Physics for their discovery of graphene; nonetheless, their technique of utilizing sticky tape to make graphene yielded solely small quantities of the material.

As a way to produce more significant portions of graphene supplies, Meyer and her colleagues began with a vial of graphite. They exfoliated the graphite — shedding the layers of fabric — to supply graphene oxide (GO), which they then blended with the bacteria Shewanella. They let the beaker of bacteria and precursor supplies sit in a single day, throughout which era the bacteria diminished the GO to graphene materials.
