Carbon-sucking nanotubes

Is there anything nanotubes can't do? The company Porifera has now developed a way of using nanotechnology to viably sequester carbon. It works by utilizing specially designed nanotubes with increased porosity and "nanofluidic" properties, which can "suck up" target molecules — in this case, CO2.
