Abstract: We describe a novel application for highly sensitive nano-biosensor based on DNA-templated gold nanowires (AuNWs) as the conducting channel to detect biotin-streptavidin binding. We confirmed that the nanodevice can be operated the highly sensitive nano-biosensor extending below the picomolar concentration regime after binding with streptavidin.
