Nanotubes Illuminate the Way to Living Photovoltaics

Scientists at EPFL have gotten bacteria to spontaneously take up fluorescent carbon nanotubes for the first time.

Scientists at EPFL have gotten bacteria to spontaneously take up fluorescent carbon nanotubes for the first time. The breakthrough unlocks new biotechnology applications for prokaryotes, such as near-infrared bacteria tracking and “living photovoltaics” – devices that generate energy using light-harvesting bacteria. “We put nanotubes inside of bacteria,” says Professor Ardemis Boghossian at EPFL’s School of Basic Sciences. “That doesn’t sound very exciting on the surface, but it’s...
