Description
Marked as a retracted article, this paper reports an enzymatic BioBattery meant to harvest energy for small devices. Vivek Saxena and co-authors built a fuel cell that runs on enzymes instead of precious metals. They tested three multicopper oxidase enzymes at the anode to find the arrangement least hindered by slow substrate delivery to the electrode. A modified protein scaffold carried the electron mediator at the cathode, where oxygen accepts the electrons.
The best pairing used an oxidase from a heat-loving microbe at the anode. Coupled to a companion BioCapacitor the team had reported earlier, the battery repeatedly charged a 470-microfarad capacitor. The authors framed structured enzyme and mediator layouts as a route to steadier enzymatic power sources for wearables and implants. The work was later retracted, so its results stand as a record of the claim rather than settled evidence.
