Abstract

A method for single-molecule detection is provided and uses a carbon nanotube having a probe entity attached thereto to define a first state of the carbon nanotube. The carbon nanotube is introduced to a target entity to define a second state of the carbon nanotube. The electrical conductance of the carbon nanotube in the first and second states is compared to detect the presence of a biomolecular entity. A system for single-molecule detection including a carbon nanotube is also provided.
