Nanoyarn Could Power Implants

Nanoyarn Could Power Implants
Aug-21-14
A new 'nanoyarn' biofuel cell able to generate electricity from the glucose in blood could use the body's own cells to power medical implants.

Although biofuel cells have been in development for decades, researchers have been stymied by some of the obstacles that impede the cells' performance, including keeping the necessary enzyme from diffusing through the cell and also keeping the enzyme active for long periods of time—which is particularly difficult in the body's environment.

In response to the challenge, researchers built a microscopic scaffold for the biofuel cell by using carbon nanotubes to create a sort of multi-walled yarn. According to Professor Gordon Wallace from the University of Wollongong, the study's co-author, the yarn provides a stable environment for the enzymes while also protecting the enzymes from things that could harm it. The team's goal is to develop the yarn-based biofuel cells to the point where they can power an implant that will stimulate nerve growth without needing an external power source.
