  • Chapter
  • First Online:
Label-Free Biosensing

Part of the book series: Springer Series on Chemical Sensors and Biosensors ((SSSENSORS,volume 16))

Abstract

Electrochemical sensors have been among the main applications of carbon nanotubes (CNTs) over the last decade, as biocompatibility and possible conjugation with biomolecules afforded by nanotubes were exploited. Amperometric sensors are among the several electrochemical (bio)sensing systems with CNTs incorporated onto electrodes to detect substances of biological and clinical interest. The layer-by-layer (LbL) technique, in particular, has been used to arrange CNTs with many materials in nanostructured films, leading to sensors and biosensors with enhanced properties to be employed in the biomedical field. This chapter brings an overview of the use of CNTs-based LbL films as amperometric sensors and their advantages as sensing platform.
