Engineered protein filaments originally produced by bacteria have been modified by scientists to conduct electricity.

Kredit: Travaglini et al. (2024), Small.In a study published recently in the journal Small, researchers revealed that protein nanowires – which were modified by adding a single compound – can conduct electricity over short distances and harness energy from moisture in the air.

"Our findings open up possibilities for developing sustainable and environmentally friendly electrical components and devices, based on proteins," says Dr. Lorenzo Travaglini, lead author on the paper. "These engineered nanowires could one day lead to innovations in energy harvesting, biomedical applications and environmental sensing."

Developments in the interdisciplinary field that combine protein engineering and nanoelectronics also hold promise for developing cutting-edge technologies that bridge the gap between biological systems and electronic devices.

"Ultimately, our goal is to modify the materials produced by bacteria to create electronic components. This could lead to a whole new era of green electronics, helping to shape a more sustainable future," says Dr. Travaglini, who is supervised by Dr. Dominic Glover in the SYNbioLAB from the School of Biotechnology and Biomolecular Sciences.
