• Two-dimensional networks of pristine single-walled carbon nanotubes (SWNTs), which cover only a small fraction of an insulating substrate (<1%), behave as macroscopic electrodes (response-dependent on the geometric area of the substrate), but with unprecedented low background currents, dependent on the area of SWNTs. This facilitates cyclic voltammetry (CV) at low concentrations (∼nanomolar), particularly significant given that carbon is a key electrode material for bioelectrochemists.
