Scholarcy highlights

  • Biosensors based on electrogenerated chemiluminescence transducers, combining advantages offered by the selectivity of the biological recognition elements and the sensitivity of ECL
  • Improvement in sensitivity and stability of ECL biosensors was obtained at the carbon nanotube modified electrode surfaces
  • We here have described a variety of ECL biosensors employing nanomaterials as modification electrode materials, carriers of ECL labels and ECL-emitting species
  • Biosensors showed improved ECL characteristics, new materials and immobilization methods are still needed in order to improve the sensitivity and the long-term stability of ECL biosensors
  • The combination of the ECL technique with other techniques could lead to the development of new instruments and provide valuable insights into molecular structures and intracellular components of biorelated species
  • With further understanding of ECL mechanisms, new highly efficient and tunable ECL systems, both emitters and coreactants, will be developed for further improving the analytical performance of ECL biosensors
