This is the best summary I could come up with:

In new work, researchers have developed a novel device that produces oxygen at the site in order to keep cells alive inside the self-contained implant.

By using electricity to split water that the cells are already bathed in, the researchers were able to produce oxygen while avoiding the production of harmful byproducts such as chlorine or hydrogen peroxide.

“Our device can be used to improve the outcomes of cell-based therapies, which use biological cells to treat diseases or injuries in the body,” said Northwestern’s Jonathan Rivnay, who co-led the study.

Combining synthetic biology with bioelectronics, Northwestern leads a collaboration with Rice University biomedical engineering professor Omid Veiseh to produce the therapeutics on site within the device.

Although previous research has explored strategies for delivering oxygen to cells, those methods used bulky equipment that is impractical for use inside the human body.

Specifically, they are working on highly stable materials that can operate inside the body for months at time – eventually using this approach to treat chronic disease conditions.
