Genetically modified proteins convert carbon nanotube to programmable optoelectronic device

Fluorescent proteins, especially green fluorescent protein (GFP), can act as the light-responsive element that transduces events through to electrically conductive transducers, such as single-walled carbon nanotubes (SWCNTs) and graphene. SWCNTs' conductance and optical properties make them particularly useful for generating active bionanohybrid systems, especially as their inherent properties can be altered through chemical modifications.
