title: Carbon nanotube biosensors with aptamers as molecular recognition elements.
abstract: In this chapter, we discuss in detail the fabrication of carbon nanotube biosensors that use a single-walled carbon nanotube field-effect transistor (SWNT-FET) as a transducer, and aptamers as molecular recognition elements. We use a patterned growth technique to grow SWNTs on Si/SiO(2) substrates, and standard microfabrication procedures are then employed to fabricate sensing devices.
