title: Edge-to-edge interaction between carbon nanotube-pyrene complexes and electrodes for biosensing and electrocatalytic applications.
abstract: We demonstrate here that the edge-to-edge interaction between carbon nanotubes (CNTs) and edge plane electrodes plays an important role in exposing a large proportion of the basal planes of the CNTs to allow enhanced π-π stacking of a pyrenyl compound and subsequent high density protein immobilization yielding large electrocatalytic currents.
