Bioengineered E. coli transmit electrons
Engineered E. coli can transmit electrons, enabling bioelectronics powered by living cells.
Why it matters
- EPFL researchers engineered E. coli to transmit electrons, a breakthrough for bioelectronics published in Advanced Science.
- Uses synthetic pathways and mediators to shuttle electrons in and out of cells.
By the numbers
- <1% of bacterial species naturally transfer electrons effectively.
- Combines direct and long-range (via mediators) electron transfer.
The big picture
- Potential for self-healing sensors, biofuel cells, or waste-processing devices.
- Expands microbial options for bioelectronics beyond naturally electroactive species.
What they're saying
- Online discussion focused more on moderation than the research itself.
Caveats
- Early-stage research; practical applications may be years away.
What’s next
- Future work may enable multi-functional bacteria-based devices for sensing or material synthesis.
