Nanotube-gulping bacteria could enable living photovoltaics and sensors

Bacteria have previously been shown to take up other nanomaterials like gold nanoparticles and glowing quantum dots. But scientists would like to use carbon nanotubes because they emit stable fluorescent light at near-infrared (NIR) wavelengths that do not overlap with the wavelengths that bacteria and other cells naturally emit. Nanotubes inside cells could be clearly detected for a long time, which would be useful for imaging and sensing.
